The best keyboard I've had so far!

I have to say, after having had this wireless keyboard for a long time now, it is one of the best that I've used. I did a lot of research before purchasing this as I had specifics of what I wanted out of the keyboard. I wanted a wireless, backlit, accurate typing experience from the keyboard. I also was willing to pay a little more for such, but not where it would completely bleed the bank account. However, I knew for good quality that will last, it would initially be a little more than your standard keyboard. Having said that, in finding the Logitech wireless illuminated keyboard K800, I felt all the details matched up and I made the decision to get it. As I initially mentioned, I have loved the thing. The battery lasts long between charges, has accurate typing of keys that even as the battery is starting to go, I don't notice much of an issue with. Love the backlit feature when you go to press a key even in dim light. Has a well made feel to it, but not too heavy. Can use even with tablets if you can plug the usb wireless dongle to communicate, as I've used it even with an iPad. Also can use if you have a supported wireless mouse as it can free up one of the usb pours on your computer. So an excellent buy if you decide to purchase that I can't praise enough!

Best warranty ever, Best quality of any peripheral

Logitech Support is beyond anything I've ever experienced. Example. I have had many of these k800 keyboards. I love them. But I also have cats that like to stomp on my keys and lay on the keyboard. it gets hair and dander crammed between the keys. sooner or later they give out. You can technically pull the keycaps off and clean, but they aren't meant to allow this and sometimes the clips break off. I ended up buying a rubber skin to get around this and now the keyboards last years. This is what i use: https://www.amazon.com/gp/product/B005RZ8104/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 I also always keep a spare so when mine finally gives out i have one ready to go. Due to the way I protect them now they last a lot longer. I bought this keyboard here on Amazon in 2013. It sat in my closet, in the box, until two weeks ago. When i opened it I discovered the space key was sticking. This is the first time I have ever gotten one that didn't work right. it was out of warranty (3 years) for over a year. I figured what the heck and submitted a ticket. 5 days later I had a brand new keyboard arrive. Not a refurb. it was new. I also now had a longer remaining warranty somehow. These people support their products and it's one reason I will always buy Logitech if possible

Still love it after 1.5 years.

I've had this keyboard for about a year and half. It's by far the best I've ever owned in so many ways. I love the quiet operation of the keystrokes. I just purchased the MK520 for an additional keyboard thinking the only difference was the illuminated keys. I was wrong about that. They keys on the MK520 are significantly louder and the texture on the plastic is not as smooth. There's a reason why it's half the price and it's not the illumination. It's ergonomically very comfortable for me, no discomfort whatsoever. Two minor gripes. 1) I wish the battery lasted longer. If I'm really working a lot, like more than 8 hours a day, I will need to recharge it every couple of weeks. And that's with the lowest setting on the keyboard light which I believe is the biggest power draw. The charging cable that comes with it isn't really long enough to connect to the computer so I usually just hook it up to my battery pack if I need to work while it's charging. I also tried hooking it up to my monitor USB but it's still a little too short. 2) While the shortcut button for the calculator will always bring it up, I have to manually mouse click on the calculator display before I can start typing in numbers and use it. So, it pops up but I can't just start calculating unless I click on it. If I reset the shortcut in the software, it will work properly again until I turn off or reset the computer. Then, same problem again. I've not found a solution to this. All in all, a wonderful piece of hardware, and I'm very picky. I returned the MK520 because it feels cheap and loud compared to this one. It has held up incredibly well. No lettering has worn off on any of the keys, they've just gotten a little shinier with use which I don't mind at all. The M310 wireless mouse is a perfect companion for it in my opinion. I prefer light, smaller mice with smooth and quiet operation and that fits the bill. My biggest gripe with that is the loud click on the center wheel, which will eventually be enough reason for me to shop for a replacement. For the keyboard though, I hope it lasts forever or I can buy an identical model when it dies.

The K800 tastes terrible, but works well for entering data

Computing systems leave me irate. Fundamentally and deeply irate. Most systems are bereft of quality assurance or acceptable user experience design. As such, I've broken many a keyboard over the years. In five-years of sixty-plus hour work-weeks I've only broken two K800s. One against the head of a coworker, the other after beating the K800 with a significantly larger and heavier monitor. This purchase is #2, and it is just as sturdy as the sadly departed prior K800. As for what most people may need: * The keys feel great. That is unless you're a nostalgic weirdo and love the archaic M-style IBM keyboards that clickity-clack at 90dB. Buy this comfortable but quiet keyboard only if you're not a sadist against your coworkers. There are better ways to get under their skin. * Logitech Unity is swell. One tiny USB dongle works for both my wireless mouse and my keyboard. * It's a keyboard with all the usual keys. That's right, unlike your diabolical laptop this keyboard has all the keys. Excel will love that you can select an entire cell region with Ctrl-Shift-End, without adding a third arm in order to manage that with some random series of secondary-function keys. I'm looking at you here Mr. Dell. Your evil will catch up with you. I've told your VP of product development about this previously. The fires of hell waft upwards, searching for you. * It doesn't have ridiculous 'ergonomic-nightmare' bubbling, angling or separation. * The battery life is impressive. I'm surprised you read this far.

The one I've been searching for

I have been searching for a wireless backlit keyboard with a calculator key for almost a year. The only one that I had found was super ugly, so I put off the purchase. I am a fan of Logitech products and my last keyboard was a Logitech, but due to wine, coffee, and tea spills, in addition to daily usage, it was on its way out. This is pretty much just the newest version of my old keyboard, so I'm happy. When I watched the unboxing review and found out that the backlight on the keys would dim after 8 seconds, I was a little disappointed. In the video, it just seemed like they were constantly turning off and you had to press a key to turn them back on. Fortunately, in my actual usage (gaming and general use) I have not had an issue. In fact, I've noticed the keys turning on even when my hand is just close by or if I pick the keyboard up. I don't think it's supposed to do that, but it's actually a bonus for me. It comes with 2 Eneloop AA batteries and the battery area is secured by a screw. It comes with 2 cables, one is for charging the batteries and I'm not sure yet what the other one is for.

The Perfect Wireless Keyboard at a Low Price

Do you ever feel like that sometimes that there are just way too many types of keyboards and mice to choose from? I've always felt that it was difficult to find a keyboard or mouse because there are just so many options. For example, I have a gaming PC, and most people would buy gaming brand products like Razer or Corsair, but me? No. I just want a simple mouse and keyboard that can do their job with good quality features. After looking around, I want to find something that was portable so I could manage videos and stuff in my room without sitting at the desk. Anyway, I found this product and I am extremely happy with it. The Logitech Illuminated Keyboard K800 provides you with almost everything you could ever need in a keyboard at an interesting price. This only cost me around 50 dollars initially, but when I received it I was happy. This keyboard has a low response time/latency which was great for my videos and games, and the back-lit keys are also watch makes it so amazing. I occasionally watch horror movies with my various friends and this keyboard always me to see what I am doing in the dark. I also can't figure out of it's a proximity thing that makes the keyboard and stuff do it. Anyway, long story short, the keyboard is also recharable and it comes with a USB 3.0 cable to Micro Usb to charge the keyboard when needed. However, I only have to charge it like once every month and a half or so as the battery for it is actually really good at maintaining it's charge. Pros: -Lightweight -Quieter -Backlit Keys -Recharable Cons: -None Overall this keyboard is amazing and has worked out really well for me. I hoped that by sharing my opinion with all you may inspire and convince you on what product to by. Thanks for reading.

Try using USB 3.0 port if you experience issues

Very disappointing. I had a wired logitech keyboard for almost 10 years before it started giving me problems. I decided to replace it with this one, hoping for the same quality. It worked great for the first week, and then suddenly started printing out the "+" character in continuous lines across the screen without me even touching the keyboard. (Edit) 1/1/18 Logitech sent me a replacement keyboard, which I have used for almost 2 months now and so far, so good. I like the way the keys have a softer tactile feel to them. Very smooth and the back key illumination is great. I keep mine tethered to the charging cable because it’s main purpose is at my desktop, but it also does fine when not on the charger. I’m thinking that there must be a bad batch floating around out there and I must have gotten one at first. Update 12/18 After 11 months, I started to have similar issues as I did with my first keyboard pre replacement. I found that the Logitech unified dongle seems to prefer the 3.0 USB port over the 2.0. Once I moved the dongle to 3.0, it functions normally. Really glad this resolved the issue, as I love the feel of this keyboard and did not want to have to switch to a different type.

The reviews don't lie

I needed a new keyboard and my friend instantly suggested the k800. The stars aligned and with the help of camelcamelcamel I tracked it on Amazon for less than $50! I use the keyboard casually, love that it's wireless, has a thin profile and can share the same USB with the Logitech MX Master. It's got a neat feature where it detects motion to turn on and you can conserve the battery by turning it off. What were the keyboards considered? -k750 -k800 Why did I choose the k800? Almost purely superficial reasons - the illuminated keys -looks more expensive (the k750 solar panels are a bit less sleek, would probably show more fingerprints)

Awesome Keyboard

I ordered this keyboard to replace my Logitech k360 which I broke. My search was limited to Logitech because I have limited USB ports and need to have my mouse and keyboard connected to the same unifying receiver. I decided to go for a more expensive option than the k360 because they last forever so I consider it a worthwhile investment. The keyboard is heavy, in a good way. Coming from the k360, which I was very happy with, it is quite obvious that this is a step up. I do not really need the back lighting so I was very happy to find out that the price premium I was paying was not only for those lights. This is a truly elegant keyboard and was well worth the extra money in my opinion. The keys have a much different feel than the k360 and most low profile keyboards that I have used. I like low-profile keyboards like my macbook which is why I don't get a mechanical keyboard but I must say that this has a much better feel than most rubber dome keyboards (note: I have only used friend's mech keyboards but never owned one). As some people have complained, the keys don't have any buffer in between them so I have run into some instances where I press the wrong key. That being said, after an evening of use I'm already almost fully adjusted. EDIT: Turns out the keys are scissor-switches, not rubber domes which is why they feel superior. The photos I've included are of the charging usb included and the male to female usb extension that you are intended to plug the unifying receiver into if it doesn't communicate well while plugged directly into your computer. I've already been using a male to female usb extension cable for my unifying receiver because the mouse would lag during games based on where the receiver would sit while plugged into my computer. The usb cables have an elegant shape to them that I've never seen a company do before and it shows how high the attention to detail is with this keyboard. The fact that Logitech took the time to make custom usb cable molds for this product is a true testament to its quality. Long story short, I am really happy with the keyboard. The craftsmanship and attention to detail is the best I've seen and my guess is that it's the best out there until you get into the premium $100-$200+ models. Well worth the price. Oh also, be sure to download the SetPoint software. Good customization options for the keys (and even more for the mouse). By using this software I realized that the mouse I've had for 3+ years has side scrolling capabilities when you push the wheel to the side.

Very satisfying

Between wireless and illuminated, this model K800 really hits the spot. Plus it feels very comfortable, just the right size, the right amount of concave-ness to the keys, just the right key press feel and response. This is my second (it was soaked, and became a science project) and my preference over all others I have looked at over the last few years. It would be nice if they were a little more coffee/wine/water proof.
