eXtremeRate Controller Grip for Xbox One, One S, One X - Skidproof & Sweat-Absorbent - Black - Modern - Gaming

These do the job and feel great. Although I had to re-adjust them which screwed them up a bit and made it bumpy on the back. It made no difference at all. I'd love to see these in different colours and multi-packs. Only negative is my controller now won't sit in it's charging dock so I have to swap batteries with my other controller.

Good product comfy an as long as you don’t mess with them they stay in place no probs

Excellent for your controller to save that sweaty hand slipping moment at a crucial moment. Great tailored fit so be careful when applying as you only get one chance, read the instructions for advice.

The product is too large for the controller; it does not align with the gaps in the plastic shell as intended. After re-adjusting it several times to search for its sweet spot, the grips started tearing and losing their stickiness.Overall, while the grips themselves are ergonomic, it's simply incompatible with an Xbox One S controller. It's a shame and an embarrassment. Do not buy it.

Boy loves them, has improved his gameplay as he is no longer dropping the controller every 5 seconds and can actually manage to shoot something in Fortnite now :-)
