First of all, I love this mouse because it matches great with my Thinkpad, it is still a great performance mouse for any computer though. Previous to this mouse I was used to a mini optical wired mouse, and I was used to it being so light, but I was getting annoyed by the cable and the optical...

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.

This mouse would a get 5 eggs - perfect, if it wasn't for this defect. I'll be replacing with a different mouse

great feel; appears to be good quality*

*Left mouse button started to 'not always click' a couple months after purchase; replaced batteries several times and blew out with can of air - seems to be a defect

The only mice I use and sold with a Lenovo laptop.

- Light and portable; - Battery last long; - Work great with a Lenovo W520; - Well build and solid (read cons

- By gentle when you changing battery trap could be fragile; But you use this trap 2 or 3 time a years; So..

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.]
