My Saitek X36 started spiking and losing calibration after only a month of use. I sent it in to Saitek to get it fixed. When I got it back, they assured me that it was fixed. Two weeks later, the same crap started happening. I went back to my MS PP2.
Ordered a Cougar and have been using it since April without a single problem (well, there was the button that popped off when it fell off my desk, but it went back on without a prob and works fine).
Everybody has their horror stories of some particular peice of equipment, from joysticks to cars. I am very happy with my Cougar, as are many others. There are many that aren't.
Different strokes and all....
