Evil Controllers' next-gen offerings have arrived, adding a bit of flair to the Xbox One and PlayStation 4's monochrome controllers. After spending some time with it, the best I can do is help you form your own opinion. What I can tell you definitively is after using a custom controller, your console's pack-in will feel boring.
After spending three weeks with a custom Xbox One controller, it isn't at all difficult to return to my stock controllers, and that's a good thing. After all, we really are essentially talking about a stock controller with a custom paint job and a new LED. Everything else here is exactly as Microsoft designed it. I won't reinvent the wheel extolling the virtues of the Xbox One's controller, Kirk already said it best:
The Xbox One controller stays close to the design of the Xbox 360 controller. That's a good thing, since the Xbox 360 controller was a pretty great controller. The new controller has the same general sleep-mask shape, its thumbsticks are still offset and it still has a round "Xbox" button in the middle. The Start and Back buttons have been renamed Menu and View, but their functions change with each app. For most intents and purposes, they're the same two buttons. Overall, it's a smooth, sturdy piece of engineering.
Evil Controllers' custom paint job doesn't feel as smooth as the stock controller—it feels downright gritty, in fact—, but the difference is texture is surprisingly quickly forgotten once you're actually playing with it. The paint itself is every bit as visually striking as the Evil's website would lead you to believe; the colors are vibrant and the patterns really pop.
Judging Evil's product strictly as a controller, it's difficult to recommend. The controller is expensive, with prices ranging from about $90 for a minimally modded controller all the way up to nearly $300 for all the bells and whistles. Evil's product isn't really designed for those just looking for another controller.
If you're looking for a custom controller, Evil Controllers is an excellent choice. The paint jobs are great, and at six months Evil's warranty is twice as long as Microsoft's.
Evil Controllers' products definitely serve a niche, but if you're in the market for one of these, you'll find an excellent controller in Evil.
