[citation][nom]Pennanen[/nom]I tried rat9 for few days, returned it and got my money back. That mouse is way too big, way too heavy and the surface material is really slippery. You can change some parts to the rubberized ones but even they get slippery if your hands sweat even a little. Removing the battery was a pain in the ass and i had to use pliers. Sensor also had lots of issues, jittering, left click got "stuck down" even tho i pressed it just once and the thumb scroll is placed under your palm.Rat 9 was one of the worst mouse i have ever used.[/citation]
Wow. I love my RAT 7, I don't suffer any of those problems (granted it's not wireless, so that's those issues out the window) It has a very unique feel when travelling which I find very appealing. I map the buttons for various functions in Photoshop/Illustrator and use it in combination with my wacom tablet. Those two scroll wheels can be used for precision horizontal/vertical panning, works a treat. I map the little targeting/precision-boost thumb button thing to the hand tool, very useful.
Not too bad when gaming either, haha.
