Review on Black Anti-Throw Handle Sleeve for Oculus Quest 2 Touch Controller Grip, Enhanced with Adjustable Nylon Wrist Knuckle Strap - Oculus Quest 2 Accessories by Christopher Penn

They are much better than smooth plastic controllers. For those with action games or sweaty hands, these are a must have. They fit exactly as they should so they won't move or slip out, and also have velcro closure so they never fall off. In addition, they have an adjustable strap that keeps the controllers in your hands. This is great if you need to adjust the goggles as it stays on your hands instead of shoving the controller in your pocket or laying it on the floor. The instruction pictures aren't that good and it took a while to figure it out. Just search for one online and see it and it will become obvious.
