The perfect keyboard

I've worked as a software engineer for over 20 years, and learned very early on that using a regular keyboard for more than a few days straight leads to wrist pain. So I've used ergonomic keyboards for basically my entire career. A few years ago I worked for a software company with a manager who refused to pay the money to buy me an ergonomic keyboard for me to use at work, so having to purchase my own I decided to give this one a try - and I'm glad I did. I use this keyboard with a MacBook Pro and have had zero compatibility issues. I tried Microsoft keyboards previously and had compatibility issues with my Mac, but with this one I've had absolutely no issues whatsoever. The keys have excellent feel and the curve in the keyboard is just right to keep my wrists comfortable without being too awkward for the rest of my family on our home computer. Some cited the durability issues, and it's true the keyboard will probably need replacing after 2-3 years, at least that's been my experience. After a while I find that some keys begin to stick and are either hard to press down or stick down and don't return back up again. At that point what I do is just go buy another one. The keyboard is so good I can't bring myself to downgrade my rating even one star for this. Since my first purchase of one of these keyboards I've bought four others. I currently have one at work and one for my home office. My only real concern about this keyboard is that Logitech will stop making it. I might have to go buy a bunch more to make sure I never run out.

time has took a tole on the poor key and it can take no more

I don't usually write reviews on products over 2 years after I have had them but this is an exception. Today I bid farewell to my wave keyboard as the 'A' key has officially stuck in a down position never to rise again. For starters, I am an individual who spends HOURS on a PC at a time. I write fiction as a hobby as well as play hours of video games. WASD are the keys that almost all games use to control characters now days... and with that, the hobby writing, and the general use... time has took a tole on the poor key and it can take no more. On to a review of the keyboard. I really loved the ergonomic feel of the keyboard and the natural slant as well as the fact that it has two heights on its little feet. I always used the 2nd height (not the base height and not the mega height), which was just perfect for the way I sat at my desk.. I actually had learned to type one handed on this keyboard due to its nature and cure. It was mainly an ability I utilized on quick searches and links.. ...I utilized the extended function keys very rarely; though they were a nice feature of the keyboard. Having them on the same as the normal function keys were a downplay as how often I used F2 and F5 alone made turning on the extended feature keys more of a hindrance than a help. ...I never understood SLEEP keys being on keyboards. Until I rendered the key null in the options I hit the key a numerous times which was annoying at best. ...Battery life was wonderful. Though I know I changed batteries just a couple of weeks ago. I couldn't tell you when I changed them last and I NEVER turned the keyboard off until today when the key died. All in all, the keyboard lasted almost 3 years and had a great feel with excellent battery life. The mouse, however, died over a year ago; can't say much for that. I remember having to change the batteries in the mouse more often than the keyboard. A negative I would find, overall, being the range of the wireless. Wireless is not infinite; in fact, the range of this device's wireless to connection is really short. I would have disconnect issues if I had the adapter on the back of my PC. On the front of my PC there was zero issues with connectivity as it was merely just 3-4 inches away from the adapter. Regardless, RIP my Wave keyboard Feb 2015 - Dec 2017...you will be missed. Just debating if I want to get the same kind or get a mechanical keyboard that allows removable keys next time. Temporarily using a tiny basic keyboard until I decide.

A comfortable efficient keyboard, I highly recommend it.

This is a great key board, I have been swearing buy it for six years now and this particular model has many followers in my office now. It is great to type on especially if you have a tendency for long days of keyboarding. It is a comfortable efficient keyboard. I highly recomend it.

TYPICAL LOGITECH QUALITY

Just received the keyboard and I'm already stoked. I have used a Dell SK 6000 E for decades. It was the first natural, or ergonomic, keyboard I bought. I have always loved the feel of that keyboard, the size of the keys and their action. I bought a Microsoft 4000 used several years ago, and I've never liked it. The crest of the upward curve (the WAVE design on the Logitech) was much too steep, more like a knife-edge ridge than a flowing 'wave'. I'm a fast typist and require a good keyboard. The keys on my new Logitech keyboard are slightly smaller and the layout a bit tighter than the Dell, but I'm getting used to it quickly. I know that I will enjoy this keyboard; I can tell from how well I can type with it right off the bat. I don't notice the noise of the keys as some people comment on. The padded hand rest is comfortable and well situated relative to the keys. I like the function keys, particularly the volume and mute buttons at the top of the keyboard. Very useful. The layout of the large DELETE, HOME and END keys is also appealing. And I particularly like that there are two DELETE keys, one large and one small in the array of the number pad. Can't wait to try out all the function keys. I'll update this review with more experience with the keyboard. I paired this keyboard with a Logitech TRACKBALL wireless mouse. I have used a trackball for decades, and I prefer them over a typical mouse. The unifying wireless combination of the keyboard and mouse is great, only one dongle.

There are many factors which combine to make this an exceptional replacement keyboard.

Background: I've been using computer keyboards since before Apple or Microsoft existed. So, as you might imagine, I've had the opportunity to use (and loathe) a lot of horrible keyboards over those many years. Before finding this keyboard, I found that I preferred the precise feel of keyboards which relied on crisp mechanical key switches made by Keytronics. Unlike most other keyboards, the key mechanism had very tight tolerances with virtually no "play" in the movement. This means the key didn't flex side-to-side or front-to-back while traveling vertically, even if you pressed the key slightly off center. Unfortunately, those mechanical key switches made a LOT of noise compared to many of their competitors. As a fast touch-typist who wrote many millions of lines of code before I retired, I can assure you the extra noise was substantial. But for me, the noise level was acceptable because the feel and tactile feedback when pressing those keys was simply excellent. I minimized the noise level by playing music through headphones while coding. Back in those days, there were no proper ergonomic keyboard designs. Over time, the perpetual bend in my wrists required when using a straight row keyboard combined with the repetitive motion to damage the carpal tunnels in my wrists. So, eventually I began searching for alternatives. The Ergonomics Craze: I admit I mindlessly bought into the "ergonomics" hype and immediately purchased the original Microsoft ergonomic keyboard design at its introduction believing it might reduce the pain and irritation of my many hours of keyboard use every day. I tried using that center-hump, split keyboard design for months, but it only seemed to make my wrists worse. Looking carefully at the way my hands moved while using that "ergonomic" keyboard, I realized the hump in the center was causing me to twist my wrists outward frequently in order to reach the outer edges of the keyboard with my pinkies. I could see the design was well suited to helping your index and middle finger move more naturally but that benefit was canceled out by requiring extra wrist motion and eliminating any semblance of natural movement for your ring finger and pinky. Ergonomic Reality Check: Being analytical in nature, I realized a truly ergonomic design would need to be more W-shaped, rather than having a central hump only. By that, I mean the keys in the center portion of the keyboard, under the index fingers should be elevated because the index finger is shorter than the middle finger. The middle finger keys should ideally be the lowest parts of the keyboard, as those fingers are the longest. Then the outer edges of the keyboard located under the ring and pinky fingers should be raised similarly to the center of the keyboard in order to eliminate the wrist rotation and finger strain required to reach those keys. Truly Ergonomic! : Eventually, I saw the Logitech Wave ergonomic keyboard design. "Finally!" I thought. "Somebody looked at the length of human fingers and designed a keyboard to accommodate the differences in length!" In addition, the key rows were also slightly curved in a way that keeps your wrists entirely straight from your elbows hanging at your sides to your hands resting near the center of the keyboard. The slight inward rotation of your forearms necessary for your closely grouped wrists to stay straight was now properly handled by joints actually designed to rotate (your shoulders.) I bought one and was quickly hooked. This keyboard reduced my pain levels noticeably, allowing me to put off wrist surgery a while longer. I haven't bothered trying any other keyboard since I started using the Logitech Wave design. At this point, everyone I know who has tried my keyboard has subsequently purchased the same model. If you are sensitive to any unusual strains on your wrists or fingers, you will appreciate the neutral joint positions and natural finger movements you are able to maintain while using this keyboard. Comparison to my beloved mechanical switch keyboards: How does it compare to my former favorite keyboards that used mechanical key switches? Well, the tactile feedback is definitely not as good. On the other hand, I feel the benefits of using this keyboard compensate for the reduced tactile feel versus classic mechanical switches. Plus, the sound level produced by typing is vastly lower than the pronounced metallic "clickety-clack" of mechanical switches. In fact, I am also of the opinion that this is the first keyboard shape which actually deserves the "ergonomic" designation. On top of that, this keyboard has good key travel, and minimal sloppiness in the vertical movement compared to most other keyboards. As a bonus, the additional functionality offered by the added media, application, and zoom keys is actually useful if you are a heavy Windows and MS Office user. (I haven't tried it on my single Mac, but I use it on all of my numerous Windows systems.) Of course, you will need to install the Logitech software bundle in order to get those extra functions to work. In my opinion, this keyboard is the ideal companion for my favorite mouse (Logitech MX Master) with both devices utilizing a single "unified" 2.4 GHz USB micro-dongle. This type of radio seems to perform noticeably better than Bluetooth for input devices. Considering all of these pluses, I would say this keyboard is definitely a step up from anything I've used before, including my beloved mechanical switches. Regarding noise levels: Normal typing on this keyboard does produce noise, but the sound it makes is mostly from your fingers hitting the plastic keys. In other words, the majority of the sound you hear while typing is not generated by the operation of the keyboard mechanism. You can tell this is true by resting your finger on a key, then pressing that key repeatedly while maintaining constant finger contact. If your fingers never leave the keys, you will discover the normal slight "clack" of your fingers hitting the plastic virtually disappears. The single exception to this is noticeable metallic clunk of the space-bar, which seems to make twice as much noise as anything else on the keyboard. Space-bar aside, the sound that remains when you press keys while maintaining constant contact is predominately a very quiet, low-frequency thump generated when the key switch bottoms out (thereby closing the contacts on the switch.) While keeping your fingers in constant contact with keys demonstrates that the mechanism is not the source of most of the sound, it is basically impossible to type anything useful without moving your fingers around to hit different keys on the keyboard. Since that means making and breaking physical contact with the keys as you move your fingers to press other keys, eliminating the previously described "clack" sound is simply impossible. I don't find the noise level disturbing, but I came from years of living with the sound of very noisy mechanical key switches, so I'm probably not the best judge of the noise levels. Compared to what I was used to, these keyboards are remarkably quiet. You may feel differently. Durability: Having cats who perform regular gravitational experiments by pushing a wide variety of things off desks, counter-tops, and bookshelves, I can assure you this keyboard can handle multiple falls pretty well. I would say the durability is quite good overall with one notable exception. The text on the keys rubs off incredibly quickly. For me, the letters "E," "N," and "S" disappeared within the first month of (admittedly heavy) use. Many other keyboards have the white letters molded directly into the key-caps using two different colors of plastic during the injection molding process. For some reason, Logitech decided to cheap-out on this particular feature. Why Logitech would make such an excellent keyboard and then paint the letters onto the black keys with cheap white paint (easily rubbed off) is just perplexing. Everything else about this keyboard is excellent quality. It even looks great with the black and silver color scheme accented by the perforated leather-look wrist rest. That is, it looks great until the paint rubs off half the keys. Then it looks like garbage. ** Hey Logitech, if you're reading this, charge me 5 bucks more and use higher quality key-caps with molded-in lettering for this keyboard. The low-quality white paint is just embarrassing. ** Why buy wireless??: I'm generally a big fan of wireless keyboards and mice these days for reasons I'll explain in a moment. This particular wireless keyboard is exceptional. Like most wireless keyboards, this one requires batteries to operate. Unlike some other wireless keyboards, the batteries last an incredibly long time in the Logitech keyboard. I type a LOT of text and after probably a couple of years of heavy use, I still haven't needed to replace the batteries. I don't do anything to extend the battery life. The keyboard power switch stays on 24/7. It's astonishing really. The current draw must be infinitesimal. There is another huge advantage most people probably don't consider when deciding whether to switch to a wireless keyboard and mouse. It is very dry in the desert, where I live. There is a lot of static electricity buildup in the air during much of the year. One day, before I switched to the wireless versions of the keyboard and mouse, my wife came into my office/shop and lightly touched my shoulder while my hands were on my corded mouse and keyboard. When she touched me, a big spark of static electricity traveled from her fingers, through me, out of my own fingertips, then through my keyboard and mouse straight into the motherboard of my computer. That single spark fried most of the chips on the motherboard. (Amazingly the CPU, RAM, and graphics card were fine.) Unfortunately for me, it was a high-end motherboard which wasn't stocked in any retail store near my home, so I had to order it online. As a result, I was without a computer for nearly a week while waiting for the replacement to arrive and then finding the time to install it. As soon as I realized the static discharge had fried my computer, I started trying to come up with a way to make sure it didn't happen again. At first, my approach was focused on attaching a grounding strip to my desk surface to rest my wrists on. But, I realized that approach would only work while my wrists were in direct contact with that strip. There was still a significant probability that I would fry another motherboard at some point. Then, it dawned on me that if my keyboard and mouse were not physically attached to my computer, it would be impossible to discharge static into my computer system that way. That's when I switched to wireless keyboards and mice and never looked back. I even keep spares around in case static fries one of them. It never has. SUMMARY: I highly recommend this keyboard for all users who are highly sensitive to the joint strain caused by the poor wrist positioning and excessive finger curl required to use more generic keyboard designs. Those who already have carpal tunnel issues may even notice a slight reduction in pain levels. This was definitely the case for me. I also highly recommend this keyboard to anyone who can't afford the expense and extreme hassle caused by frying their motherboard with a static discharge. It's easier, faster, and cheaper to replace a wireless keyboard than to replace a motherboard. Lastly, I recommend this keyboard for fast touch typists. I was fast already, but I believe this keyboard increased my speed by at least another 10%. It's amazing how fast your hands can move when all of the joints are moving in their most natural orientation. In fact, I'd generally recommend this keyboard to anyone who spends more than a couple hours a week at their computer. Non-touch typists may find the disappearing key labels to be an issue, but for most, the rub-off white paint is really only a minor nuisance. Keep in mind, you could always repaint them or buy stick-on labels for the blank keys. Each time my keys have worn off, I simply replaced the keyboard. Highly recommended!

Excellent choice for those experiencing pain or cramping from extensive computer use.

I was considering purchasing either this Logitech K350 Wave wireless keyboard or the Microsoft Natural Keyboard after I started getting pains in my hand, which would always be worse after a long day at work, where I would be using my keyboard and mouse constantly. I finally decided on the Logitech K350 Wave and I do not regret my decision. My main concern was that the Logitech was not contoured enough to the natural position of my hands. The Microsoft Natural seems more of a drastic change from the typical keyboard position, and I thought that would be better. After carefully reading reviews though it seemed like the Logitech Wave was a good fit for comfortable typing. I find the position to the keys to be comfortable, and I like how the keys are quiet. I currently have it paired with the Logitech MX Master 2S, and with these two items my hand/wrist cramping has all but disappeared.I definitely highly recommend this keyboard.

In simple words -- Just amazing..worth the price.

Absolutely amazing and fantastic to use..The keyboard has a ton of options and the keyboard just feels great to use. I had a microsoft mouse and keyboard bundle earlier. The bluetooth connection to the mouse and or the keyboard kept dropping every time I lock and move out of my desk or wake it up from sleep..I had to turn off bluetooth on my laptop and switch it back on to connect both of them. It used to be very irritating with it. First of all, this keyboard and mouse comes with a dongle. So connection was a jiffy...I connected the dongle and within seconds, I started using the keyboard and mouse. The keyboard feels little heavy but it is solid in design and the keys are very strong. You get a feel that it is sturdy with its first look. The way pattern of the keys, the very big space bar along with the palm rest feels very comfortable. The keyboard has a ton of options. To name a few, you can configure to open word, excel in a function click. They are huge volume control button at the top. There are multi media buttons, camera button, media center button, Zoom, calculator buttons. One special button I loved to see was the power button to the top right corner. It was easy to send my computer to sleep. There is a special button to switch between active windows. The mouse looks big when and comfortable in the hand. The motion is seamless and it has all the default buttons. Along with it, I love the side buttons which has a option to do CTRL + TAB by default. This helps me a lot at work while I keep shifting between tabs. Overall, I am very satisfied with my purchase.

Still the best keyboard available (IMHO)

My daughter, my brother and I all use the Logitech Wave Keyboard and have for many years. I purchased this model after my 12-year-old Wave keyboard had problems with sticking keys or keys that were hard to press. It had also grown to be quite noisy. I am very happy with this newer keyboard. In my opinion, the keys are quieter and have smoother action than my old keyboard even when it was new. I hope this model lasts for 12 years as well. I also hope that Logitech keeps making these. At my age, I am not sure I could adapt to another keyboard as I have been using a Wave type keyboard for 30 years. I also have used trackballs instead of using a mouse since the mid-80s. Trackballs are getting harder to find — at least for desktops. There seems to be a selection for gamers, but I am not a gamer. I hope Logitech keeps making trackballs as well. I realize this is unrelated to the keyboard review, but I am hoping Logitech gets the message anyway.

I've used Wave keyboards for over a decade. Pretty close to perfect!

I've owned a lot of keyboards, and once I got on these Wave keyboards about 10 years ago, I've never switched off of them. I like the play/feedback I get off of this new model of the Wave keyboard. Even better than the play/feedback with my older models, which I did like. There's a good feel of 'confirmation' in the keys when you strike them. But yet not over-bearing confirmation, like those old-school spring-loaded 1980's IBM keyboards threw off. That big padded perforated section perfectly places your heels to negate any strain on your wrists (that might lead to Carpal Tunnel Syndrome). Your hands always feel pretty close to "at rest." That section wipes clean very easily, too. The big silver buttons can be reprogrammed to do whatever you want. If you load up the Logitech SetPoint software that you download from their website. I use them to open specific folders that I often access. I reprogrammed the Sleep button to be a Restart button. And you don't HAVE to use the Logitech software unless you want that programming feature, basically. Otherwise it's a plug and play keyboard ... that functions perfectly even at the BIOS setting level. I also like that the audio/video controls at the center top don't require any set-up. When I strike up/down volume or mute, they work with any application I run. I have zero reception/distance/obstruction problems in keeping the USB receiver plugged directly to the back of my desktop, down on the floor, facing a wall, next to my desk. To be fair, the very first one I owned, again bought ten years ago, did have a bit of a problem in that regard. At that time the Wave keyboard shipped with an entirely different USB receiver, a larger one that looked a lot like a flash drive; I had to bring it closer to my desktop with a USB extension cable. Two ordinary AA batteries will keep this keyboard running for several years. And there's a little indicator that lights up when it's time to change them out. Too bad there aren't any indicator lights for CapsLock or NumLock, like old-school. (How many obscured passwords have I typed in incorrectly over the years not realizing I had accidentally turned on caps aiming for the tab key!) The one thing I REALLY don't like about them is that the white paint on the keys tends to wear off too easily. I've owned about four of these Wave keyboards over a decade and they all do it. This keyboard comes with a five-year warranty, so from now on I am sending in an email to Logitech asking for a new key whenever one wears off. Also I prefer the old-school Logitech logo. The font on this new logo looks, to me, sort of over-baked, so over-modern as to be a bit gaudy. Oh, well. I am sure Logitech paid some marketing firm millions of dollars to create it, so I guess it's my shortcoming. LOL. And it would be cool if it had a backlit option, like those gamer keyboards, since I work a lot late at night. I guess you can't have it all. This Wave keyboard has been one of the top-selling keyboards in the marketplace since its introduction so long ago. That kind of says it all.

though I like my Logitech K360 and other Logitech mice

I decided to use bigger keyboard and mice at home, though I like my Logitech K360 and other Logitech mice. Pros: 1. well-designed keyboard. The palm cushion is a little soft which makes you wrist feel comfortable when you are not typing. It may take some time to get used to the gradual wave-shaped contour, but I think it's good too. 2. 18 programable keys. 3. The size of M510 mice is exactly what I look for. Mouse Dimensions (height x width x depth): 2.56 in (65 mm) x 4.72 in (120 mm) x 1.61 in (41 mm) 4. Battery life is long. According to Logitech, the keyboard has 3-year battery life, and the mouse has two years. Both of them use 2 AA batteris. Cons: 1. No Caps-lock light in the keyboard. 2. Home/End/Delete/PageUp/PageDown key layout is not good. I often press the bigger Delete key when I tend to click the End Key. 3. The Logitech SetPoint software (6.67) does not support M510 mouse. I can pair my other Logitech devices in the Unifying Software and manage all of them in SetPoint, but M510 is an exception. I had to download another software Logitech Options to manage M510.
