However, the R1 and L1 are very slack in their positions and make an annoying rattling sound when the controller vibrates

My only complaints about the product would be that the D-Pad can require very deliberate inputs to accomplish diagonal inputs (I play a lot of MKX, so this can be an issue), and the vibration motors make a strange and noticeable sound (I turn the vibration function off).

I was looking for a controller with a fairly decent and responsive D-pad considering I would be playing classic titles such as Streets of Rage 3 and Breakers Revenge (Neo-Geo) with this

I don't like the D-

I can only recommend this controller to anyone who doesn't care for having a good D-Pad
