I needed a converter to use my 360/PS3 stick (Eightarc Fusion if you're wondering) on PS4 and Brook no longer sells their other adapters for Revain so I went for opted for these rather than potentially cheap counterfeits from other sellers. Plus first class shipping compared to the shipping costs at another online store for things like FocusAttack. I connected it to my PS4, pressed the home button and there we are. No lags or missed entries or anything.
