If you’ve worked up a sweat in an Oculus game, you’ll already know why you need these! Grips help you keep the controller where it’s supposed to be in your hands.
AMVR Touch Controller Grip Cover
Some products cover up the sensors on the controllers so you lose tracking, but we have these highly-rated ones and have never had issues with tracking. They remove (and go back on) easily when it’s time to replace the controller batteries.
An Oculus user has an Etsy store with a variety of Quest accessories. We haven’t personally tried his stuff (yet), but he’s got hundreds of 5-star ratings, so if you like the idea of supporting a small business, check these out from TycoTech3DPrinting.
Another highly-rated option if you have an original Quest: These Kiwi straps aren’t really a grip, but rather a strap that wraps around your knuckles to keep the controller in place. We’ve read great reviews about these.
