Firstly I purchased this to use on PC, and microsoft said it would work on normal bluetooth – this was/is only partially true as it will work for a while over normal bluetooth then disconnect. As far as I know this has been a known issue since its release and still isn't fixed. ( Buying xbox adapter for pc fixed the issue… ) Secondly, these have a high fault rate – from sticking buttons to analog stick drift, they're not all made equal at all. I know 3 people who bought this controller and 2 had stick drift. Luckily I didn't have this issue but I think it needs to be noted when considering buying a ‘premium’ controller.
