UPDATE: Still Awesome ! Every feature I want and using the same mouse on my two laptops is awesome!

I have laptop two computers on my desktop and, until today, two mice. I paired the MX Master 2S with unifying receivers on both laptops, downloaded the Options software from the Logitech website and had the new mouse working seamlessly on both laptops in a matter of minutes. The mouse itself if wonderful, but the Flow technology is amazing. I can even copy and paste text from one computer to the other. The mouse is very well worth the money, especially when you consider is can take the place of up to three ordinary mice. Bluetooth connectivity is a bit choppy for any mouse I've tried. It's OK but the mice work so much more smoothly with the unifying receivers. I used the receiver from my previous mouse in one laptop and the one the came with this mouse in the other. If you don't have a spare receiver, you'll either need to purchase one or use Bluetooth on the additional systems. The mouse will switch between/among up to three. UPDATE: After almost two years, this mouse continues to exceed my expectations. I use it all day for work and could not be more pleased with it.

Look no further

I bought this 4 months ago. It's improved my life in almost every way. I work in film on the post-production end which means I spend long hours every day on my machine. I used to use an apple mouse with the roller ball center wheel. I hated that every few hours I'd have to rub the ball back and forth on my jeans to get it working again because of oil or dust on the sensor, but I didn't want to switch to a different mouse because I needed to zoom and pan and scan using that button. It finally came time to upgrade so I bought this not knowing how I'd feel about seperate wheels for horizontal and vertical scrolling. This was totally worth the money. It took maybe a few minutes to get used to. No learning curve really. I use it on the free spin setting and it's changed my whole experience. It feels much more organic. I love the weight and feel of it. My hand stays much more relaxed because of it's ergonomic shape. And I love that youn can customize button settings for each application you use. I haven't tried setting it up for multiple computers but I do love the thing and would reccomend it to anyone who's looking to improve their mouse setup for video work.

My favorite mouse

I have been using an original MX Master (which I’ll call MXM for brevity) at the office for the past three years and it is by far my favorite mouse, until the MX Master 2 (though for my uses they are largely the same). Scroll wheels on mice have been a real pain for me in the past, it seems like scroll wheels on every mouse I’ve used prior to the MXM were junk. They were always janky where clicks wouldn’t register, or scrolling just wasn’t smooth. I was talking with a guy at work a few years ago about this and he let me test-drive his MXM for an hour and I loved it, so I immediately purchased one. I have used it with zero problems for the last few years, and I’m still addicted to quickly scrolling through web pages, code files, spreadsheets, etc by using the smooth-as-butter quick scrolling feature. For me the scroll wheel alone is worth the price, but of course it has plenty of other really useful features. At home I was using an MX Anywhere mouse because I travel frequently, so the smaller form-factor is nice. However, it does feel a bit too cramped and when I use it I miss the ergonomics and smooth scrolling. I finally decided to get another MX Master (this one being the MX Master 2). I don’t know why I didn’t buy this sooner! It’s basically the same as the original MXM with a few added features. The MXM 2 supports “Flow” software which allows you to seamlessly use the mouse across multiple computers (up to three) without having to manually change the connection on the bottom of the mouse. You can also copy and paste files across multiple computers, provided you copy/paste by using the mouse itself rather than keyboard shortcuts. The MXM 2 also supports higher resolution (up to 4,000 DPI) and longer battery life. The thumb gesture button on the MXM 2 does feel a slight bit mushier than the original but for me it's easier to click. I see a lot of people complaining about the forward/back thumb buttons being set too far back making them uncomfortable to use, but I have adapted to using them a bit differently. Rather than pulling my thumb back and searching for the correct button I simply keep my thumb in its natural position and rock it up/down, letting the side of my thumb hit the buttons. It only took me a short time to get used to doing it this way, but it feels completely natural. This mouse is super comfortable to use all day long. It is a bit on the larger side so if you have smaller hands then it might not be ideal for you. The MXM really does work on every surface I’ve tested on. My coffee table has a glass top and no other mouse works fluidly on it, except the MXM series. I don’t do much PC gaming outside of playing Civ, which doesn’t require twitch accuracy, but I’ve heard a number of people say it’s not an ideal gaming mouse. I will take their word for it, so if you’re looking for a gaming mouse then I’d do a little more searching around. That being said, for productivity it works flawlessly. Finally, if you have an original MXM and it’s still working well for you then I don’t think it’s worth upgrading unless something like Flow is something you will find really useful.

Fantastic mouse with amazing features.

I've had this mouse for less than an hour, and I already love it. It is incredibly comfortable in my hand, has a great weight to it, and feels really solid. It was also super simple to setup. It started working the second I turned it on. I didn't even have to pair it with the Unifying receiver. I always use gaming mice. My last 2 mice have been Razer Mamba's (Gen 1, and 2016 Tournament edition). One of the major reasons I like gaming mice is that typically all the buttons are assignable. I always assign Ctrl+F4 to one of the thumb buttons to make it quicker to close tabs in the web browser. In my experience, most regular mice don't have that feature, or they do but to a much lesser degree of customization. This one does. And it does it really well. There are tons of preset options, or you can assign key combos. The thumb rest button is also really neat. There are a bunch of pre-programmed gestures it can emulate, which can come in handy. I don't see this replacing my Razer Mamba for gaming (it's not accurate enough for gaming in my opinion), but this will definitely be my full time mouse for everything else, both at home and at work. It's prefect for productivity. The Flow feature lets you move (as well as Copy/Paste) seamlessly across multiple computers, which is fantastic. Of course, for it to be really useful a keyboard that does the same would be nice. They exist, but I'm not giving up my mechanical keyboard.

Excellent mouse, great for multiple computer owners, PC & Mac. Very customizable, and comfortable.

Love this mouse. It took a day or so to get used to, I've been using a track pad at home (media center keyboard), and an apple mouse at work, so getting this was sort of a new experience. But once I started using it, I loved it! I don't use all the various buttons too much, but I do play some games where they come in handy. The variable mouse scroll style is really nice. By clicking the button below the scroll wheel, it changes the mechanics of the scroll from smooth and seamless, to a notched system. Also you can program the mouse to quickly switch from one machine to the next, up to 3—whether it's PC or Mac. Also you can customize each of the buttons exactly how you want with the downloadable software on Logitech's website. Which btw, is a very simple, elegant, and beautifully designed out software. Finally the battery is rechargeable, and you can just plug a USB cable right into the mouse for charging. The only thing that I don' love is that there aren't any notifications of my mouse battery. Maybe it's just something I haven't enabled or figured out, but my mouse will just die without any warning. Good news is, that with a couple minute charge, I'm back in business for the rest of the day.

Excellent Mouse

I had been using a thumball for the last several years, which started to stick a little bit. I assume the stand-offs were just wearing down. The new mice have a lot of added features, so I decided to try one since I'm on the computer all day at work. Wasn't sure if I would be able to take advantage of all the features because I'm not able to install any software on my work computer but was pleasantly surprised. Installed the dongle and the mouse fired right up with no issues. The weight feels nice, a little heavier than the old mice that come with the computers but gives it a solid feel. The texture/feel feels nice and will be easy to wipe off and keep clean. The vertical hyperscroll is really nice, as well as the horizontal scroll wheel at the thumb position. The forward and back buttons work well but are right on top of each other, wish they were spaced a little more, but work fine. Mouse also has a button below the scroll wheel that either gives you the normal detent scroll or unlocks the wheel so it free-spins for hyper scroll. Very happy that all the default functions work great without having to load any software, just means I can't customize button functions or select alternate actions which isn't a problem for me. Haven't had it long enough to know how long the rechargeable battery lasts but it comes with a USB cable for charging and the box says it's good for 60 days so it probably won't matter for my office use. So far I couldn't be happier.

Best Mouse for two computers!

I have a MacBook Pro 15" (2018 6 Core) and a 2017 27" 5K iMac. The logitech flow software just slides between them so easily and my productivity is through the roof! The software even wakes a sleeping computer. The button under the thumb rest which I left on Mission Control is the most convenient thing in the world. You can switch through your open apps so quickly. The auto scroll sensing is a dream and I find that is works right when it's supposed to. Plus it's totally fun to play with. The side thumb wheel for scrolling is great for long excel docs. Some people complain of the back/forward buttons being awkward. You get used to them. Battery life is great. I have had 2/3 bars for 4 weeks now. Yes it actually tells you the battery life right on the mouse! Comes with a micro USB in the box as if I didn't have like 100 of them. Still nice. Some people complain about the bluetooth switch being on the bottom... if you read the directions and set it up correctly then you should never have to touch them... Shocker! I highly recommend this mouse to people with more than one computer on their desk. :)

Great mouse for work and gaming

If you've ever used an older wireless mouse from the previous generation (4+ years ago), you might remember that most of them have fairly poor battery life, especially the ones with built-in lithium ion batteries. Like me, you might have also had experiences where your wireless mouse would have weird performance issues or would take a while to "wake up" after not using it for a while. Logitech has been making wireless mice for a long time. It's clear from this device's nearly flawless implementation that they've taken an iterative improvement approach to their product, with a goal of making it longer-lasting, more durable, more convenient and more reliable while also meeting the performance expectations of both gamers and power users. This is a fairly expensive device as far as mice go, but the build quality and all the other aspects of this mouse are so great that it's well worth the price. I bought one for my office and one for home. My favorite part about this mouse is how it's flexible between the Logitech Unifying receiver and Bluetooth. The only problem I've ever had with this device is that certain sub-par Bluetooth implementations (such as the one built into my desktop) doesn't provide a very reliable signal, but that's probably because the signal has to travel through my PC case and desk to reach the mouse. The Unifying signal is basically flawless and far superior to Bluetooth. The other part I really like is how I didn't have to tweak or customize it at all in software for it to feel just right for me. It didn't take me any time to adjust; it felt perfect from the start. The side buttons on the top left "ridge' are a little difficult for me to press with my thumb because they're so far back; I wouldn't have to bend my thumb as much if they were a little closer to the front. But I don't use them terribly often so it's not a showstopper for me. The scroll wheel dynamic adjust between free-wheel and click mode is awesome. I really like it because it's easy to scroll a long distance through a big document with one swipe, but if you want to scroll a few lines at a time you can do that, too. Overall this is the best mouse I currently own. It's just as good as gaming wired mice from the competition, but the battery life of 3-4 months between charges means the typical disadvantages of wireless mice aren't really a factor.

I really like the feel of the MX Master 2S

I upgraded from a Logitech M545. You can see the M545 on the right in the photo. The MX Master 2S is a wireless mouse, but I was charging it at the time of the photo. The MX Master 2S looks a lot grayer in the photo because I had a bright lamp directly over it. The actual color of the mouse resembles #3F3F3F (google that hex code to see the color). I am used to medium to small sized computer mice. I decided to order a new mouse because I was upgrading the rest of my Mac setup. So far, I really like the feel of the MX Master 2S. The mouse will fill your entire palm. PROS: 1. Feels great. I originally thought I would hate the thumb rest, but I really enjoy it. 2. The free scroll setting for the mouse wheel is very smooth. 3. The thumb scrolling wheel feels great. It is not easily bumped by your thumb. Even if you do bump it, it will not scroll much, if any at all. It has a little weight to it. 4. The side buttons don't feel awkward, I don't have to reach my thumb very far to press either one. It's a very natural reach. 5. The customizability with the Logitech software. You can set custom actions for different applications. 6. The thumb rest is also a button (harder to press than a mouse button so you don't accidentally press it). 7. Wireless. I have a bluetooth keyboard (Logitech K811) and didn't want to clutter my workspace with wires. CONS: 1. The mouse wheel in it's "normal" mode (not free scrolling) is louder than expected. Keep in mind that I am used to smaller mice where the mouse wheel is virtually silent. When the wheel is in "free scroll" mode, it is virtually silent. 2. The larger grip might feel weird to you if you aren't used to it. EDIT after a few weeks of usage: My only complaint is that this mouse, at this time, appears to have issues with my MBP mid-2015 Sierra v10.12.5, when more than two bluetooth devices are in use at a time. It's rare for me to have more than two bluetooth devices running at once, but on occasion I'll plug up my PS4 controller to play games. The mouse will sometimes skip/jump around, but I can't confirm if this is an OSX issue or an issue with the mouse itself. I have customized many buttons to perform different actions in different applications. This pairs extremely well with other programs like BetterTouchTool which let you map custom keys for even more custom key bindings.

Its good but its got issues... not perfect but probably the best mouse in the world right now.

So Im giving it a 5 because its a pretty solid mouse. I have been using the mx series for a long time and its nice. But I wish it felt less plasticy... like I don't like the Magic Mouse from Apple because its too low of a profile and its horizontal scroll gesture makes using adobe products almost impossible... but the build quality of the magic mouse is 2nd to none. Its amazing. I have the iMac Pro and the black Magic Mouse with it glass and metal housing is really beautiful and SOOO solid in your hand. Logitech is still in the plastic world and their products feel cheap. There is A LOT of room for improvement and build quality. Just so happens that most mice in the world are terrible... one plastic piece of crap after another... at least Apple is trying... but that low profile is just terrible to use over several hours of work. Anyway, Logitech has a lot of room to grow.
