I only bought this kit to replace pads under L2 and R2 triggers. I play a lot of FPS and my R2 only started to lock in about 70% of the tap. (This makes driving games impossible as you can only press the gas pedal 70%. This means NO burnouts in GTA 5, no drifting in NFS etc.) All in all I only had to swap out the trigger pads. After replacing the new pad with my R2 trigger it still only registers about 70% (as seen when plugging the controller into a USB port on your computer). and then put a HONBAY spare under L2. Now my R2 is working at 100% and my L2 at 70%. So I can confirm that the pads are DEFINITELY the cause. These HONBAY pads did not solve my problem at all. I can't comment on the rest of the kit as I only used trigger pads.
