So my mice arrived yesterday. And IO 1.1 is unusable from the beginning, probably damaged by the shipping cause M1 and M2 buttons are so hard they make my Kana v1 with TTC seem soft... Didn´t except WMO buttons be so mushy either, M1 and M2 are somewhat failed on that one to. Don´t know how to explain it but they are placed at the right side so the M2 button is sticking out a little bit over the edge of the side, M1 is to far in from the edge. Not a very big deal, still usable, just a bit annoying. Didn´t like the feeling of the switches though. The IE 3.0 M1 & M2 buttons was very soft and nice. The glossy top felt good (glossy felt good on all three), but the sides on 3.0 took the record from Savu of slippery material. When draging the finger over it it felt smooth but completely impossible to grip. The shape of 3.0 felt great to hold but when using it felt wierd. When I was playing with it and would make a 180 in CS I always pulled the crosshair up when turning right or down turning left. Obviously i held it wrong somehow. WMO felt best ingame, good weight and size, liked the size. Doubtful whether I will use it or not because of the mushy M buttons.
The search for the perfect mouse continues. Waiting on a KinzuAdder V2pro/3G. Since I liked the WMO and the Kinzu being closest to that I hope my search will end with KA. Good shape like WMO but with better sensor, OMRON switches and DA cable instead of WMOs very stiff and thick or a braided crap.
