For the most part this is a good product. Comfortable, durable, and help with traction, but those are a few issues. They are difficult to place on the racquet, cause the racquet to fail to return to center, and can cause the racquet to become stuck in one direction if not properly centered. I had to replace the joystick because it caused my left joystick to aim straight when I let go of it, causing the character to keep moving in most games unless you were touching it. My right joystick started doing the same until I removed the cover. If this is corrected, they will be almost perfect!
