"Not too bad - not too great either"3.0 starson by jeeves86
Pros: --extraordinarily comfortable
--charging base included
--quality could be better
--charging dock is obtrusive
--switching from wireless to wired not exactly easy
Summary: I've used this mouse for about a year and a half until it died. It was pretty expensive to buy, but I wanted a wireless, full size Razer mouse. It's comfortable to use and fits my hand perfectly with a long-lasting battery and glides like a dream. Adjustable dpi settings are also great.
However, the build quality could be so much better, particularly for the price. After a year and a half of moderate usage, it needs to be replaced. The buttons are over responsive, double-clicking at random points. For buttons that are already a little too sensitive, this is an issue. And for the price, it's an even bigger issue.
