Ergonomics are great. My previous mouse was a Kensington Mouse-in-a-Box. This mouse has a similar form. Sensor seems very accurate, or good enough for my use (desktop publishing, including Photoshop work). Scrolling is nice. Clicking is very quiet.

Great touch and very quality build. The white color looks elegant. The unifying receiver that can be customized to control any keyboard and mouse that you want is a smart innovation and easy to set up and use.

Great every day device. Operates quickly,smoothly and quietly!! Excellent value and extremely high battery life. Will purchase another one for my laptop as I’m not a fan of the track pad on the note book.

[This review was collected as part of a promotion.] The M650 was a perfect fit for my hand and makes it easy to maneuver the curser across the screen. i like the style and feel of it. For my choice i couldn’t have made a better one. Thank You.

[This review was collected as part of a promotion.] I will only buy a Logitech mouse from now on! It fits comfortably in my hand, glides well, and doesn’t stick. It’s portable and easy to connect. And I love the pink color!

[This review was collected as part of a promotion.] Like the size of it. Dealt with a lot of lag when using it with dongle. Still trying to figure out how to set up button. If it wasn't for the size I would of returned it.

I lvoe this mouse, It's easy to use, battery is like lasting forever. No cable to tangle up and the buttons are as SIlent as you could ask for along with being very smooth

[This review was collected as part of a promotion.] Does all the things you need, bright blue is nice and cheery. plugged in and just started working.

I have a G403 which was great until the scroll wheel started glitching. I have a 2-year-old so go figure. Looking to replace it with this after I saw someone using it at a workstation. The blue really pops out in a good way.

[This review was collected as part of a promotion.] Really nice mouse. I prefer a mouse to TouchPads. This one is really nice. It interacts greatly with programs.
