Although this initially looked like a bargain compared to other controllers several things have let this down, so beware I say, I may have been unlucky but the quality of this thing is suspect.
* Syncing; it can be a real pain trying to get the controller sync'd with my PS3, didn't have this trouble with any others.
* Controls, after less than a weeks (fairly light) use the right analogue control stick really had to be shoved to the right in order to induce "run".
Overall, it's not giving me the impression of something that's going to last.
