Pros: I love the programmable gestures! I listen to a lot of music while I'm working. So, I configured my gestures as: Move Right = Next track, Move Left = Previous track, Move Forward = Volume up, Move Back = Volume down, Gesture Button Click = Pause/Play
Cons: Only complaint is that the Logitech software doesn't load immediately when the computer.
Pros: Easy switching between devices. Often work between a lap top and a desktop this allows quick switching between the two.
Cons: I've also use the Logitech keyboard which connects to 3 devices. You have to let the keyboard connect first before the mouse otherwise the keyboard may not connect or it may take 20 or more seconds (longer than I'm willing to wait having to switch back and forth often). If the keyboard connects first the mouse just takes a couple of seconds.
Overall Review: Even with the ordered connection I still feel I received good value. I would purchase this again and I would recommend it to a friend.
Pros: multi-device works well
long battery life
good build quality (not cheap glossy plastic)
Cons: Not as great as the MX Master mice but feels like just as good quality and way longer battery life.
Overall Review: Would recommend this for folks that have multiple devices (RF USB and Bluetooth) and switch. Have this on a Windows 10 laptop with the RF USB dongle and iPad with Bluetooth. Works well.
Overall Review: By far the best mouse i've owned.
Pros: Fast and reponsive.
Overall Review: Would buy again.
Overall Review: Very comfortable and reliable. Super long battery life. Precise pointer positioning. Feels great to the touch. Can be used with up to three devices. Durable and well-made.
Pros: Multi-function programmable, large size for people with big hands, battery lasts a long time, smooth scroll wheel.
Also, the wireless reception was excellent, no problems even at 2 meters.
Cons: Did not have button selectable DPI function.
Overall Review: I would recommend.
Pros: It works smoothly. Seems well built - typical Logitech quality
Cons: This is the first Logitech mouse I've purchased that is a disappointment. It does NOT do what is implied in the literature. It does not easily switch from one computer to another. Switching to a computer with the "unifying" adapter works well. But then trying to switch to a Bluetooth computer requires going through a partial re-pairing each time you switch computers. It is not quick and easy as implied. The second complaint is the documentation is incomplete. There is a button on top of the mouse which is not even mentioned! I can find no information for what it does!? Further, the "Options" software leaves a lot to be desired. The ad speaks of button assignment change but it is NOT offered in the program. (I would like to disable one of the buttons as it impairs using the mouse on certain other software.) All in all, the documentation is very poor.
Overall Review: Perhaps Logitech will eventually make this mouse right. The documentation speaks of using "unifying" adapters but does not list or show where or how to acquire them. It appears that the company rushed this mouse to market before getting the documentation finished - or the associated "option" software complete also.
