Customer Ratings & Reviews

This mouse has a good feel in my hand, it weighs what I would expect and all of the buttons are thought out well. My only issue is having my thumb button press the gesture button, this is just a weird movement for a thumb but it's a human issue and not a mouse issue per se. Battery life has been excellent and I have the mouse on bluetooth but can use the dongle if needed. My only wish is that the dongle had a storage spot underneath.

Most amazing, COMFORTABLE mouse I've ever had. I have larger hands, carpel tunnel, and other wrist issues. So glad I pulled the trigger on this purchase. Definitely a great investment.

this is buy fair the best mouse that i have ever bought its fits almost any size hand boughtfully and its very smoth to use and the options are endless

Got it as a gift for my cousin, looks great and feels great! He loved the mouse

Excellent tracking and features, I use it as my every day mouse at the office

Great mouse so far. Was using Logitech's Performance MX mouse. The MX Master has quite a few options, some very useful and some not. Just wish the page forward/page back were a little larger and a little more room between them and the thumb wheel. I use the thumb wheel to control the volume to my speakers and the center wheel to mute music when I push down on it.

Excellent mouse.. finally pulled the trigger and it hasn't let me down.. I have fairly big hands which might be needed bc this guy has some size to it.. horizontal scroll wheel works well.. Haven't played with programming the buttons but looking forward to taking advantage of the myriad of capabilities this thing possesses. Also can't underestimate ability to pair w/ bluetooth to three computers and switch between them instantly with a push of a button on the underside of the mouse. Mainly purchased hoping to upgrade reception (distance mainly) but also tracking from my go-to Logitech M-510 mouse and it indeed does respond at greater distances with flawless tracking.. very exciting. Well worth it.. pull the trigger and don't look back you won't regret it.

I'm using this mouse to write this review now, nearly 6 years later. It's still going strong and is my favorite mouse. It's super comfy and ergonomic and works excellent.

I'm a Windows 8 PC user; Have NOT tested on MAC so can't speak for that. Okay so this lovely looking mouse feels great on the palm (I have average sized hands), impressive ergonomics and design. Features top notch, literally you can customize all the buttons to work your way. $100 worthy ? Debatable .. BUT BAAAAM !!!! All those good things are put to shame when we talk about the Software and Connectivity. Terrible Terrible and I mean Really Terrible Connectivity both via Bluetooth & USB dongle ... there is a certain offset in the connection when you turn on the Computer; takes just a tad bit to get going. I had a hard time connecting it through usb and then assigning bluetooth as well. The button assignment to perform different function sometimes vanishes and then you have to fire up the software again and hit refresh and what not, Switch the mouse ON & OFF several times to get it back to working as you desired. Seriously Logitech ? For buyers, I would say this is good mouse just not $100 worthy but has all the fire power and features if you really are a power user.

When it comes to buying mice and keyboards, Logitech wins HANDS DOWN. Using for personal and business, RELIABILITY is of the utmost importance and I've been a heavy user of Logitech for a long time ... especially since the MX series originated. I finally had to retire an over-used MX Revolution or whatever the latest high end mouse WAS ... and moved to the "new" MX. Works even better on my glass desk, feels even better in the hand, and apparently allows for switchable connection to 3 different devices. Scroll wheels (horz. & vert.) are smooth as silk with a solid feel. Well done Logitech!

Bought this mouse coming from the MX Performance. It uses a new software so now you have to have another install not just SetPoint if you are using other Logitech products. feels like you are holding it a bit sideways and the button layout is terrible.

After using the magic mouse with my laptop for a while I just could not handle how uncomfortable it was to use. After trying it out in the store I decided to get the mouse based on its initial comfort and size. It fits my hands perfectly and has worked flawlessly with my MacBook. I would highly recommend this mouse.

I bought this Mouse for work use with CAD software. I really like the auto-switch on the free-spin mouse wheel. It gives great control when needed & still has the free-spin option. Previous versions use the wheel click button to switch modes but I use the wheel button often in CAD so that WAS a no go. this charges easily & will run for a week or more at a go.

I have extra large hands and have for years dealt with using smaller wireless mice, this one solves that effortlessly. It has more programmable buttons and a better feel and usability than the next model down the m705, which I still own and use for travel. This mouse paired with the k800 wireless keyboard, make designing and doing 3D modeling very easy.

Everyone's been raving about this mouse lately, and I was looking for something comfortable for work, so I stopped in and picked one up. Not even 5 minutes with it and I already plan to return it. The mouse is comfortable and tracks well, but what I hate is the scroll wheel. I own Logitech's G502 and before that the G500. Both mice let you click a button just behind the scroll wheel to go from click-to-click to free scroll, a feature I love and saw was available on this mouse. Apparently I didn't understand what the box means by "auto shift from click-to-click to hyper-fast scrolling," because when you're on click-to-click mode it will literally switch to fast-scroll automatically if you spin the wheel fast enough. I tend to be a fairly fast scroll wheel user already, and I don't like that the click-to-click setting automatically switches to fast-scroll when you spin the wheel fast enough; makes me feel like I've lost control. Just now I tried to scroll up quickly with the mouse in click mode, only for the fast-scroll to kick in, then when it switched back the page scrolled down a bit as the wheel "reset". Glad this mouse is working for others, but it's not for me. I'll be returning it and will probably just get another M705 or a G502 for work.

I wasn't going to buy this mouse at first because of the price...and I thought I'd never use all the features...but I thought I would give it a try...I am glad I did...It took a little while to learn how to use all the buttons...But once I got used to it...I love it !!!

Great and very customize-able, feels good in hand and the only complaint is an "out of sleep" lag.

Avid Apple product user and have been using a Magic Mouse for 4 years now but a couple of weeks ago the laser went out on me so had to look into getting a new mouse. Wanted to try something different and after some extensive research; found that the Logitech MX Master would be a good fit for my needs. The customization of the many buttons is what sold me on this mouse. The Magic Mouse has smart touch features which are represented by buttons and scroll wheels on the MX mouse. The transition was farely easy and after a week of usage; I can say that I have adapted to the differences very well. The only draw back that I am struggling with is the bulkiness of the MX Master mouse. I fiddled around with the mouse in the store for awhile and it felt ok but it is taking longer than expected to get used to the size, especially coming from the Magic Mouse. I suppose over time I will get used to it. The contour shapes of the mouse are comfortable on the hand and I feel much less fatigue than using the Magic Mouse. Overall it is a great mouse but takes some getting used to if you are moving from a small or low profile mouse.

Great battery life, smooth performance, great ergonomics. I owned the previous MX mouse back in the day and this is better on almost every level. I only wish it had a forward button on the side but that's a minor complaint.

This is easily the best mouse I've ever used. I ended up buying one for at work and one for at home. The dynamic scroll wheel is awesome and the gesture support with the side thumb button is great.
