The mouse works fine, but the problem is with the material. The shiny plastic on the sides of the mouse makes it so that it feels that my fingers are wet when you touch it even though they are not. It is due to the material of the plastic. I'll be taking it back.

This one of the best mice I have ever used! It plugs into a USB port and there is no set up, so it c

Batteries last a long time; works great

It's easy to misuse the middle button

The right click button failed after 3 days, and the middle click requires a precise press to activate instead of triggering the forward/back buttons.

navigate very well, and comfortable

Overall I thought this was a good buy, though the full price is a bit high for the quality.

Great portable laptop mouse; Tiny USB receiver, decent ergonomics, good small size for travel; Love that the USB receiver can be stowed inside the mouse

If you have a small to medium-large hand size, I can recommend this mouse without any hesitation. Excellent weight, form and performance. For me, not having to use a dongle/port is more than worth the price.

Was not available at store but customer service was helpful in locating online and shipped direct to customer. It was easy to connect and worked as advertised. Price was in normal range as expected.

I would say that I have average size hands that are probably larger than the majority of female hands. I found the mouse to be too small. It was especially difficult when I tried to do work that required detailed mouse manipulation. it was uncomfortable and wore my hand out.

I purchased this mouse along with my X1 Yoga. Works flawlessly every time. It was easy to set up and connect as well. It's compact size makes it easy for travel. I would have no problems recommending this to anyone. [This review was collected as part of a promotion.]
