"it works for couple of minutes when i start my system, I have 3 different windows 7 laptops, it didn't work for any of the system. Still i am holding this mouse & checking every week whether it works or not. Conclusion: beautiful mouse without having life."
"I got this mouse with my new laptop back last December, but only started using it about two months ago. Initially, it was excellent, with smooth cursor control and a comfortable design. I was very happy with it, until about a week ago when I turned my laptop on and the mouse no longer worked. I've been given the "USB not recognized" error only once; other than that it simply wont connect with the mouse. I've tried everything from rebooting the computer, replacing the batteries, cleaning the USB, and scouring the internet with no results. It was good at first, but I'm upset about how quickly the reliability gave out. For 40 bucks you can get a very good mouse from Amazon that'll last much longer. While I do like the design, the short life span has put me off the mouse."
"This product works absolutely perfectly with my Lenovo IdeaPad Z575, it provides stunning ergonomics and precise cursor movement. The casing is stylish too, and the battery life is unbelievably great. However my main concern with this product is whether it has the ability to switch off by itself after leaving it on for long periods of time (eg. sometimes i leave it on overnight). Will the bttery life and overall product life be affected if it is left on continuously or does it have the ability to save power? I don't know...if i understand how it works it would be good to know. Anyway, this mouse is great and super practical...hasn't let me down in any way. Prime example of Lenovo showing their exceptional product quality and reliabilty :)"
