The controller is definitely worse than the original controller. Nevertheless I do not regret the purchase. It is slightly larger than the original, I like that. The R2 and L2 button are installed too deep.
For little action-laden games he is well suited for first person shooter probably rather less.
I use the controller with the batteries that I bought for the camera. They last longer than I can play at a time.
Buy the part, there are significantly worse.
