You didn't happen to get that from Amazon did you? I am looking to get that one and a white one however the reviews are all very flakey and suggest that they're not genuine controllers. For £33 or whatever it is I would have thought they would be genuine?
I got mine from YesAsia. I had the same issue as you. Was going to get from Amazon or Ebay, but too many people saying fake/not fake. So just grabbed from YesAsia as far as I know, and from looking around, they're legit and don't do fake stuff.
I would just avoid 3rd party sellers with the controllers, seems to be a minefield. Should be fine if you make sure it's Amazon themselves selling them though, but that's only going to work for the white one, as the candy blue was never released outside Asia.
Not too bad from YesAsia though. They have free shipping on the controller and if it's your first order, there is $5 off (voucher code, can get it online by searching I think). Came to £41 for it, but it got through without getting hit for import.
