The Razer Wolverine is by far the best controller I’ve ever purchased. Got it now… 7 years ago and it’s still just an absolute champ. The initial price may scare off some, and the fact that it’s wired, but it’s the best damn controller I’ve ever used.
Flappers are 2 can be mapped to existing buttons (I have mine as up/down on the D-pad), and the other 2 raise/lower sensitivity of the sticks. So I can hold a flapper while sniping to get real precise.
It also has two little toggles on the inside between the bumpers which I have mapped to left/right on the dpad, which is really nice because I don’t have to take my fingers off the sticks, Witcher 3 this is amazing because what’s how you pull out a specific sword.
