Mouse works anywhere, does skip sometimes on glass, but it does work unlike most optical mice.
It's small but smart, working very well on my Thinkpad.
Then I need an additional mouse for my work computer and decided to try the other similar model (Lenovo 06P4069 Optical USB Wheel Mouse) also at Amazon with over 4 stars and hundreds of reviews.
When I received the other product and tried it, I immediately this model is superior, since I don't need a mouse pad for it to work perfectly on my white colored tabletop, while the Lenovo 06P4069 Optical USB Wheel Mouse needs a mouse pad to work.
Typical cheap mouse, it works but the design isn't great.
Its an okay mouse.
The only thing wrong with it is that the cord is way too short.
That became such a nuisance that I replaced it with a wireless mouse.
Mouse wheel stopped working after a three-week light usage (less than 0.5 hour per day.
As a fan of the X1 Carbon, I thought this mouse would be a nice addition.
