Logitech MX Master Wireless Mouse – High-Precision Sensor, Speed-Adaptive Scroll Wheel, Easy-Switch up to 3 Devices - Meteorite

For the first year I had this mouse it was fantastic. I purchased two more to use in other locations I need to work. I use them on an Apple MacBook Pro 13" 2017. Over the last four months the cursor now jumps around the screen due to lag. Ive done everything I can think of to fix it, bluetooth, unifying device, turn bluetooth off, uninstall Logitech options, move closer together, farther apart, turn off wifi. Logitechs support articles go back two years and only ever say to use the unifying device. Apple doesnt say anything about anything ever. Im not sure what to do with three mx masters I can no longer use. The MacBook hasnt been great either with its two USB-C ports both losing connection with the monitor regularly.

Mouse is as described by many outstanding reviews and YouTubers, it is very responsive and the most comfortable mouse I have ever used. My only concern is that my PC laptop decided to stop allowing the Bluetooth to work, I called Logitech as I thought it was the MX Master, as it turns out its my laptop so as a work-a-round Im using the dongle. It to works great. Lastly, a shout out to Logitech customer support (August) for exceptional care and understanding, he went above and beyond getting me up and running, and answered my call in record time. No waiting or getting shuffled around, best customer service ever...many companies should take lessons from Logitech customer service!!

This is the 2nd one that I have purchased (home and work) I love the feel and ergonomic shape of the mouse. The buttons are in great locations and easy to program. My only complaints are; no removable rechargeable battery (battery dies --throw away buy another) and it still uses micro USB for charging. this means I have to have 2 cables one micro USB (for the mouse) and another USB-C, for newer devices (tablets, phones etc..). other than these minor complaints. I would highly recomend getting one or two of these mice.

My Microsoft Wireless Mouse 5000 scroll wheel got damaged after about 3 years of use and I was looking to find a great mouse to use daily. The reviews told me the Logitech mouse as the best in the price range I was willing to spend. I completely disagree. I didnt like the feel of the scroll wheel, either in step or free mode. I didnt find it that comfortable at all and just felt cheap in my opinion. Went back and bought another Microsoft Wireless Mouse 5000 with a keyboard at the same price. I really believe Microsofts Mice and Keyboards have the absolute best/smoothest feel. Everytime I try a different brand, I am disappointed.

Im not sure if mine was just a fluke or not, but the top wheel seemed to be heavier on one side. Whenever I would scroll to the position on the page that I wanted, the wheel would start to roll one way or the other until the heavy side was down. No problems in ratchet mode because it couldnt spin on its own. Other than that, this mouse is gorgeous and fits my hand perfectly. Logitech makes you use their Options software instead of SetPoint. SetPoint, in my opinion, makes the mouse more customizable and has the "Snap-to" option in which I miss with the new Options software. Hopefully Logitech will work out the software issue to do justice to one of their premier mice. I am returning the MX Master and going with the Logitech MX Master 2S Wireless Mouse. Hopefully I will get what I pay for.

I originally bought this mouse so I could quickly switch between two PCs at my desk. Im in utter shock they put the device switcher UNDERNEATH the mouse instead of as another button next to the scroll mode button. This horrible implementation completely defeated the purpose of having one mouse to rule your workspace as it is extremely cumbersome to flip the mouse upside down and press a button every time you want to switch devices (need to use two hands). Even worse, if you only have 2 devices, the mode switcher requires you cycle thru all 3 devices meaning you need to remember to press the switch button once if you want to go to device 2, and twice if you want to switch from device 2 back to device 1 (because it needs to run thru device 3 whether you are using it or not). Being a G502 user, this mouse also has a really bulky arch that doesnt feel as ergonomic as my G502. I might get used to it, I might not. Likely returning this week though by the sole fact they put such a critical button in such an illogical location.

Two things. One is the top mouse buttons (left click and right click) are too easy to click. Its sorta hard to rest your hand on it without accidentally clicking it. For a big mouse that you rest your hand on it should be firmer to click. Two is the right hand ring finger position is terrible. Not good on top of mouse, and setting on the right edge uncomfortably when overhanging it. Also was missing the USB receiver (box was sealed). Otherwise a real nice mouse. Update: Logitech sent me a receiver. Thats good on them. Mouse wheel is great, best Ive had. Really can get a long spin out of it. If youre ok to have index finger resting on left mouse click button , and middle finger on wheel, and ring finger on the right mouse click button, then it would be ergonomic for you. For me the left half of the mouse is really ergonomic, but not the right half because I dont want my ring finger on top of the mouse. Im going to keep it. Good enough to do that.

Apparently to use this with bluetooth you need a PC or laptop that can detect low energy bluetooth - must be very low energy, I have to say. My laptop can communicate with my bluetooth speakers from 50 feet away but cant detect this mouse thats just a couple of feet from it. Sometimes I will see UNKNOWN device pop up but cant connect regardless. There is a unifying receiver that comes with it, but thats another slot on my USB dock that I have to lose. The mouse is heavy too so if you have a habit of lifting your mouse occasionally, it can get tiring and strain on your wrists is a real concern. There is an extra hidden button where the thumb rests and while nice to have an extra feature, clicking feel sucks. The only way I can tell that it worked is when it worked. No tactile feedback at all. Thumbwheel is very useful for me. I assigned it to speaker volumes so I can easily change audio levels without having to find that sound icon. Even a multimedia keyboard, which I have, is inconvenient. Just for this reason, I am keeping this mouse.

Update: Ive used it for a few days now... Absolute trash of a mouse. The fast scroll wheel is so "loose" that you only need to move the mouse and not touch the wheel for whatever your looking at scroll the page. The ratcheting system (press the ratchet button) feels cheap as can be, it sort of feels like its engaging some sort of plastic mechanical arm inside, often times have to press it twice to get it to engage or disengage. I cant be bothered to return it, but I will go buy some Logitech MX Performance mice. End update. Good mouse over all, but... If you are coming from the Performance MX you may be surprised to find out that its a lower profile mouse. It doesnt fit my hand nearly as well as the Performance MX mouse does. Also the Logitech Options software/settings is down right primitive compared to the original Settings for the Performance MX. There are so many settings available in the Settings software compared to the Options software that its almost down right criminal. The grips while both have rubberized side grips, the Performance MX mouse is more "sticky" for lack of a better term so my hand sticks to it better, the new MX S2 is very slick so I find myself having to squeeze it harder to hold on to it. One would think looking at that nice geometrical pattern of the side grips that its going to grip better but it doesnt. Im quite sad that they discontinued the original Performance MX device even with its faulty clicker buttons (used to go through them every six months) as Id gladly pay more to keep using a superior mouse like the Performance MX. Im now looking to buy up Performance MX mice so that I have them well into the future.

I like the look of this newer MX version, very sleek and the copper trim is quite eye catching. Im a long time performance MX user, there are differences in the feel of the mice. The older version sits slightly higher, meeting your palm more comfortablely and providing added support. This new MX mouse sits a little lower has taken some getting used to. The mouse is quick and works well on multiple surfaces. I love the ability to pair with multiple RF devices with the switch of a button, very nice upgrade. Overall I would recommend.
