A worthy replacement for the price. Below is a list of pros and cons I found with them. Pros: Cheaper bang for the buck. They look good and are very similar to the original devices. 5 pairs of triggers L2 and R2 with springs. Cons: The springs are much weaker than the OE parts. The snap-in release posts are slightly smaller than the OE parts and tend to pop out when the case halves are reassembled. This can cause the trigger to fail. Be sure to check the function before you put the screws back into the controller. The triggers are slightly larger than the originals and protrude from the back of the case. When reopening, be careful not to lose the spring. This is mainly because the postal problem is less than OEM. All in all a worthy replacement, just take your time assembling and testing before powering down completely.
