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
NIMASO’s 2025 MagSafe ring does almost everything: magnets on both sides, a 360° rotating ring and a ring long enough to work as a stand. But next to the SYNCWIRE ring I use every day, it is 10 g heavier and its movement feels less refined. With only a ¥200 price difference, I still prefer SYNCWIRE.
What I tested
- NIMASO MagSafe ring, 2025 model (double-sided magnets, 360° rotation)
- SYNCWIRE double ring with 360° rotation, which I have used daily this year
- Both on my iPhone 17 Pro Max with several cases, a kitchen scale and calipers
A viewer asked which of the two to buy, so I bought the NIMASO to compare.
What I found
| Ring | Weight (measured) | Thickness (measured) | Price at the time of recording |
|---|---|---|---|
 | 45.8 g | 6.2 mm | ¥2,499 |
 | 35.8 g | 6.1 mm | ¥2,700 |
Weight. Thickness is basically the same, but SYNCWIRE is 10 g lighter, roughly 20–25% less, and you can feel it.
Rotation and hinge feel. Both rings rotate on their own, so you don’t have to spin the whole phone against the case. SYNCWIRE turns slowly with a little resistance and feels premium; the NIMASO feels slightly loose. When lifting the ring, the NIMASO snaps out, then moves freely, and clicks at full extension. SYNCWIRE moves with one smooth, even resistance, which I prefer.
Stand angles. The NIMASO lifts in two stages and reaches about the length of a double ring, so it works well as a stand, but it stops at a fixed maximum. SYNCWIRE opens further, giving a little more freedom.
Color. I ordered NIMASO’s black, and it arrived in a copper-like shade. It suits red or brown cases, but looks a bit off on black ones.
The box includes a metal ring for phones without MagSafe (with a small gap, like an eye-chart “C”), a manual, a warranty card and an alignment guide. One request for both brands: add a small bump or dent where you lift the ring, so you can find it by touch without looking.
Who it’s for
- SYNCWIRE: you want the lightest option and a smoother, more premium feel
- NIMASO: you like the copper color, use a red or brown case, or find it on a big sale
If the NIMASO drops to around ¥1,000 in a sale, it becomes very easy to recommend. As I said in the video, if this ring had come out a year earlier, it would have been a huge hit.
Watch the review
The video is in Japanese. YouTube’s auto-translated captions may help. Useful timestamps: 6:00 rotation feel, 11:20 thickness and weight, 12:00 my conclusion.
Limitations
This is a first-impressions comparison, not a long-term test, and magnet strength was judged by hand. Prices were Amazon Japan’s at the time of recording.
