Mad Catz R.A.T.5 Gaming Mouse Review: - AWESOME Gaming Mouse! This is definitely the best mouse I have ever owned.
The mouse just looks so cool, but it fits in my hand perfectly after some adjusting.
I do a lot of gaming, and the different programmable profiles really helps me quickly switch between different games. The precision aim is pretty cool, but I use it as another button mostly.
One thing I would recommend before buying is not getting a soft pad. I bought the SteelSeries Qck Gaming Mouse Pad, but it was too soft and the mouse sunk into it. I would recommend a thing pad or a hard one. I use an old playing card mat and it works great. http://dlvr.it/4hkGXF
