Vortez tried the Razer Wildcat
A quote from the article:
Razer have had a presence with the Xbox console for a while, releasing the Onza controller for the Xbox 360 in 2011. The Onza was a well received entry by Razer, yet many felt it was poorly implemented with many complaints about build quality. Since then, Razer have been working away to refine their game pads and have since released various controllers including the Sabertooth for 360, and now the Wildcat for Xbox One. Enthusiast/tournament game pads are now in full swing, the overwhelming popularity of the Xbox Elite controller solidifies this fact, yet some haven't quite found the perfect partner with the Elite controller. Some find it too heavy for prolonged use and others are getting frustrated about the back paddles are too easy to hit, causing mistakes/misclicks in game. These properties are strong blows from Razer, with the Wildcat weighing a mere 260g, and having 2 additional bumper buttons on the top, and two aluminium triggers on the underside.Razer Wildcat Review @ Vortez
