I bought this mouse when I bought my laptop around nine months ago. I really like this mouse. It fits my hand nicely, it works great (unlike the Microsoft mouse I bought to replace it, and later returned). The flaw that kills this product is the rubber center of the wheel. Over the course of the first 5-6 months the rubber expanded due to use. It eventually expanded to the point that it jammed the wheel and made it unusable. The wheel would not turn forward or backwards. For the next couple months I adjusted to using the wheel simply to click, but eventually I grew tired of not being able to use it for more than that, and decided to replace it. If I could find this exact same mouse without the rubber wheel I'd buy it right now.
