Spigen Dual Pop MagFit Slim Review: A 16 g MagSafe Ring With a Too-Strong Magnet

This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.

Quick take

Spigen’s Dual Pop MagFit in the slim version is a MagSafe finger ring that weighs 16 g on my scale and measures 3.2 mm thick. It disappears in a pocket, and the soft silicone loop never hurt my finger. It has no kickstand, though, and the outer magnet is so strong that the ring tends to stay stuck to MagSafe car mounts and stands when you pull the phone away.

What I tested

Spigen Dual Pop MagFit (slim type), Marble Grey: 2,390 yen on Amazon Japan at the time of recording
My everyday SYNCWIRE MagSafe double ring (rotating, doubles as a stand) for comparison
A leather MagSafe case, Apple’s own iPhone case, a MagSafe car mount and a Peak Design MagSafe stand

What I found

Very thin and light. 16 g and 3.2 mm, versus 35.6 g and 6.3 mm for my SYNCWIRE double ring. An older ultra-thin SYNCWIRE ring was also 3.2 mm but heavier at 20.7 g — and mine eventually cracked; it seems to be discontinued.
Soft, stretchy loop. The centre is a jelly-like silicone. It was easiest to lift the ring slightly before slipping a finger in, and then it grips the hand nicely.
Strong grip on the phone. Pulling on the loop feels like it might tear, so I slide the ring off sideways instead.
The outer magnet is almost too strong. On a strong MagSafe car mount the ring stayed on the mount when I took the phone. It slides off in a couple of seconds, but it’s annoying if you dock and undock all day. A gentler Peak Design stand let go of it without trouble.
Works with Apple’s case. The Apple logo sits right in the middle of the ring, and the slightly weaker magnet in Apple’s case made the ring easier to remove.

Side by side

Ring	Weight (my scale)	Thickness (measured)	Stand
Spigen (slim)	16 g	3.2 mm	No
SYNCWIRE double ring	35.6 g	6.3 mm	Yes (rotating)

On Apple’s case, the logo shows through the ring

Who it’s for

Get it if you only want a finger loop to stop drops, carry your phone in a pocket, and rarely use MagSafe mounts. Skip it if you want your ring to double as a kickstand, or if you put your phone on a strong MagSafe car mount several times a day.

Limitations

This is a short hands-on test, not a long-term durability review. Weights and thickness are from my own scale and calipers, the price is Amazon Japan’s at the time of recording, and how strongly the ring sticks will depend on your case and mount.
