I love these buttons, they look stylish with the other mods on my controller. However, when I installed it for the first time, I noticed that the R1 button was still stuck. I wrote to the seller about this problem and each time he quickly returned the correspondence and corrected the situation. I haven't tried the new R1 button yet, but once I do I plan to report the results. They are metal and appear to be of excellent quality, FYI.
