Review on 🎮 eXtremeRate Black Silver Carbon Fiber Bottom Shell for PS4 Slim Pro Controller - Game Improvement Replacement Parts Back Housing Case Cover for Playstation 4 Controller JDM-040, JDM-050, JDM-055 by John Boyce

This assessment will be similar to the front bezel review. But that's backshell. Something is wrong with the seams, they are very noticeable. There was also discoloration, making the shell stick out. Essentially, the gap is a decent size and taller than the other case. It might not bother you, but it's really not very comfortable to hold in your hands. The seams don't line up and that's because it lifts up when you hold it. Installation is not difficult but can be time consuming when testing with original PS4 controller skins. The same problem with seams. That's very bad, because it's a really beautiful shell. I ended up sending both of them back. I wish this company would sell them as a set and better quality control could catch that. Who knows, maybe I have a bad body. I won't change it as installation is quite easy BUT again installation is time consuming if it doesn't fit properly then it takes some time to pack everything back up and reassemble the original controller. (Make sure to pay attention to the two ribbon cables).
