Black Phone Ring Holder - Finger Grip Stand for Cell Phone Cases | Secure & Comfortable Grip for One-Hand Use, Perfect for Commuting, Watching Videos & Taking Selfies

The rings are nice, slim, and sturdy. I have used these for at least a couple months and they have no scratches, adhesive has never gotten lose, and are still rigid in position. I tend to play with my rings as a fidget toy, so most wear down and swing freely after a bit, but this one is still working as new. It also holds very firmly to the magnetic holder in my car. I will be buying more.
