There has to be something I'm not doing properly or something. However unless I'm getting something wrong, I always have a hard time getting it to work on PS2, it's like I have to try 30 times before it works on a PS2 setup. It is a bit wobbly but very very little, which I think is common for all this type of things (I heard the Wii actually had that except they hid the shaking). It took me a while to set it up properly (both calibration AND finding a good setup irl), both the thing is really good. I've received the Aimtrak and played a few hours both on PC and PS2.
