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 Joel Young

They do exactly what they say. The instructions aren't very good, but I figured it out and it's not that hard. The materials are durable and work really well once you get used to the feel. A pain in the A$$ to replace the batteries as you have to remove them but that's really a minor complaint. But for the price of 9.99 I think they are better. I'm not sure if the benefits are worth $20
