The grips are slightly difficult to get attached to the original ones. You need to ensure the area near the release button is fully engaged. Once connected they feel good. My right controller grip arrived broken, and the battery was totally dead. It took 14 days to arrive from China to the US. Customer service was quick to respond and are sending another right grip and battery from China. So, it will be 28 days until I can fully use and test them out. I suggest paying a little extra and get them from Amazon.
