Overview
A MagSafe-compatible ring grip, model SW-RH990, built with N55 magnets on both sides so it holds a phone with one hand and still attaches to a MagSafe car mount without removing the ring first. The same back side sticks to other metal surfaces such as fitness equipment or a fridge.
Most ring grips only grab the phone; this one is magnetic front and back, which is the feature worth noting. The ring folds out from a gear-and-spring mechanism that clicks into position rather than free-spinning, and a flat-bottomed stand doubles as a kickstand in either orientation.
- N55 magnets, double-sided design
- Up to 10 lbs hold with included metal ring
- Rated for over 6,000 fold cycles
- 360 degree rotation, 90 degree flip
Who it's for
IPhone owners with MagSafe who want a finger grip that stays attached when the phone drops onto a car mount, or anyone who wants a ring holder that can also stick to a metal surface around the house or gym. Not useful without a MagSafe-compatible phone or case, since the magnetic hold depends on it.
Pros and cons
- Double-sided magnets dock straight onto a MagSafe car mount
- Back side sticks to other metal surfaces around the house or gym
- 360 degree rotation with a 90 degree flip for horizontal or vertical use
- Clicking gear mechanism instead of a loose-spinning ring
- Requires a MagSafe-compatible phone or case to engage
- Included metal ring is needed to reach the higher rated hold strength
Performance notes
The phone-side magnets rated at 2.6 to 3 lbs of hold jump to roughly 10 lbs when the included metal ring is added underneath a case, which is the mechanism behind the strong-hold claim rather than the magnets alone. The gear-and-spring hinge is built to survive over 6,000 fold cycles, aimed at the ring being opened and closed constantly rather than left extended.

Yes, the double-sided magnetic design lets it dock onto a MagSafe car mount with the ring still in place.
What is the metal ring included for?
