EWA MagOne (3rd Gen) Review: An 18 g MagSafe Ring With Everything Built In

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

Phone rings are handy, but most of them make your phone thicker and heavier. The EWA MagOne (3rd generation) is a new kind of MagSafe ring that manages to be ultra-thin and ultra-light while still packing in rotation, a stand and magnets on both sides. On my scale it weighed 18.3 g and measured 3.3 mm thick. If light weight is your priority, I think this is the best MagSafe ring you can get right now.

What I tested

EWA MagOne (3rd generation), which comes in seven colours. I bought it myself
Compared it with two other popular rings: the GripMate double-sided magnetic MagSafe ring and the Spigen Dual Pop MagFit
Measured thickness with calipers and weighed it, then used it as a grip and as a stand

What I found

The box includes two spare rubber bands, so you can swap the inner band when it starts to stretch. It is nice to see a ring designed to last.
Calipers showed about 3.3 mm, and the scale showed 18.3 g. I have tried more than 20 rings, and getting all these features at this weight and thickness was a real surprise.

Measuring the EWA MagOne thickness with calipers — About 3.3 mm thick, 18.3 g on my scale

The outer metal ring works as a stand at any angle, and the inner rubber band rotates so you can slip a finger through it. The two parts have clearly separate jobs, which makes it easy to use.
The inner band only fits one finger, so some people may find it a little tight.
It is magnetic on both sides, so you can stick it straight onto a car mount and other MagSafe accessories. When you do, keep an eye on how strong the magnets on your case side are.

Putting a finger through the EWA MagOne rubber band — The inner band rotates; the outer ring is the stand

GripMate: you can put two fingers through it and the hold is excellent, but it weighs around 40 g.
Spigen Dual Pop MagFit: a very thin, simple ring at just over 16 g on my scale, so about as light as the MagOne.
If you want every feature and still want it light, the MagOne struck the best balance of the three.

Who it’s for

Anyone who does not want to add weight to their phone, or who wants to keep a slim phone looking slim, should take a close look at this one. If you need a two-finger grip and do not mind the extra weight, the GripMate holds better. If you only need a basic, thin ring, the Spigen is an alternative.

Limitations

The weights and thickness are from my own scale and calipers. This is based on my own use of one unit, and I did not test long-term wear of the rubber band. Colours and availability outside Japan may differ.
