Well, I was going to include a picture in the review but Amazon.com is being obstinate. Anyway, the mouse looks exactly like it does in the photos, with the exception of the bottom photo — it looks better in real life, because it's all in English and not Chinese.
This mouse is EXTREMELY light! But it's not flimsy. In fact, it feels perfectly manufactured — like it should be more expensive than it is. The mouse clicks, as advertised, are practically silent. (Wonderful for gaming.)
I would essentially rate this mouse as flawless apart from two things which I find weird. The lesser problem is that the side buttons are very, very springy, and have a lot of travel before the click. Nonetheless, they do have a solid click, and they're not gummy at all. Maybe it's designed that way to prevent accidental clicks from the thumb when gripping the mouse tightly. But I can live with it.
The only major (tiny) problem was the on/off switch on the bottom of the mouse, which has a raised groove for manually switching it. It actually bottoms out on the mousepad / surface during normal use, and since my first environment was on fabric upholstery, that little groove on the toggle would catch on the threads with every single move.
So I used a dremel and inside of ten seconds had the groove gone. That's a total hillbilly solution, and I normally never do stuff life that, but man... the mouse is now functionally flawless. It was way easier to fix that than I thought it would be. And it's the best mouse I've ever owned. Buy it.
