I own 4 of these. Bottom line - the controllers work just fine and were about half the price of an official one. They work as advertised, but do have a few quirks that occasionally remind you of their lower price tag. PERFECT FOR YOUR "HAVING FRIENDS OVER" CONTROLLERS, BUT PROBABLY NOT GONNA BE YOUR FAVORITE.Of my 4 controllers, 2 took oddly long to sync to the system (just had to keep trying for a few minutes, then worked just fine). One of them vibrates oddly loud (its honestly kinda funny), and another occasionally drops connection but for the most part is perfectly usable. So if you want to save a good bit of $$, these controllers are a solid buy.
