Overview
A metal ring grip that sticks to the back of a phone with 3M adhesive, rotates 360 degrees and folds flat to 180 degrees for a stand angle. Aimed at anyone who wants a secure one-hand grip and a built-in kickstand without swapping cases.
The grip only works because of the adhesive underneath it, and Syncwire is explicit that the 3M pad does not bond to silicone, leather or fabric cases, only smooth plastic, metal and TPU. That single line matters more than the ring mechanism itself when checking fit.
- 360 degree rotation, 180 degree fold
- Zinc alloy and metal plate build
- 3M VHB adhesive rated near 5 kg hold
- Doubles as a magnetic mount plate
Who it's for
People who carry a bare phone or a hard plastic or TPU case and want a fold-flat kickstand for video calls or hands-free viewing. Not for anyone with a silicone, leather or fabric case, since the adhesive will not hold there.
Pros and cons
- Folds flat and rotates a full 360 degrees for any viewing angle
- Metal backing plate works with magnetic car mounts
- Hinge rated for 6,000 folds
- Adhesive will not stick to silicone, leather or fabric cases
- Not meant to be repositioned often once applied
Performance notes
Syncwire specifies an ultra-slim 0.014 inch zinc alloy build with vacuum ion plating, which the listing says resists color fading better than standard electroplating. The 3M VHB pad is rated to hold under roughly 5 kg of pull, and the fold hinge is rated for 6,000 open and close cycles. The metal backing plate doubles as a mount point for magnetic car holders.
