Used to use the Logitech G9x, bought a second one when my original died, then I bought the Steelseries Sensei which I currently use. Really love this mouse, took a few days or so to get used to the shape etc.
Works great for BF3, WoW, LoL, SC2 and many other games via Steam.
Anyone know a mouse that has a different clicking mechanism. I had 2 nagas, 1 cm spawn, 1 g400, and now my g600, all of em double clicking problem. 6 mos to 1 year. I just use the autohotkey script now on my g600 and its great, makes your computer immune to lightning fast double clicks by buggy mouse. But i want a mouse that i wouldnt need to run a background program just to make it work correctly.
