This is a floating hand grip for Insta360 cameras. I've used it a few times, but it has no noticeable scratches or stains. -----Quoted from the official website---- The perfect non-slip floating hand grip for your water adventures. Compatible with GO 2 by using the action mount adapter. Diving case not included. When attaching to the floating hand grip without a diving case, the GO 3/GO 3S must be assembled with the quick release mount. The quick release mount is not required if you have a diving case.
