Hows the condition of the mouse? And for $25 I would say it is a pretty good deal, try to get it for $20 if you can, haha!
It would help if you tried the mouse though. Do you like the feeling? Do you not? If you like the feeling of the mouse and you play games at high sensitivities, then I would suggest you get the mouse. If you're like me, and didn't really like the shape of the mouse, and don't play at "insanely" high sensitivities, I would suggest getting something else. I ended up going with the Deathadder.
