memumi Aramid Fiber Case Review (iPhone 17 Pro Max): Better Button Design, No MagSafe

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

The memumi aramid fiber case covers the buttons with simple holes instead of the big cut-outs found on most thin aramid cases, including PITAKA's. I like that shape a lot. But it is not a MagSafe case: rings and stands barely hold, and it fell off my car mount. If you rely on MagSafe accessories, look elsewhere.

What I tested

memumi ultra-thin aramid fiber case for iPhone 17 Pro Max (not MagSafe). The patterned version was 5,399 yen at the time of recording; I bought the blue one on sale.
For weight comparison: memumi 0.3 mm case, a SwitchEasy ultra-light case, CASEFINITE Frost Air Ultra Magnetic and the PITAKA MagSafe aramid case
A MagSafe ring, a MagSafe stand, a car mount and a MagSafe charger

What I found

The listing says 0.5 mm and 12 g. My scale said 21.9 g — heavier than the PITAKA (20.6 g).
Other measured weights: memumi 0.3 mm case 13.5 g, SwitchEasy 12.5 g, CASEFINITE 24.1 g.
Buttons and Camera Control are easy to press through the holes.
A MagSafe ring sticks, weakly. A stand works if the phone faces slightly upward. On a car mount it fell off, so I would not use it in a car.
MagSafe charging works.
The lip is only slightly higher than a glass screen protector, so do not expect much protection for face-down drops.

Who it's for

People who want a light aramid case that protects the buttons and do not use MagSafe accessories.
Not for anyone who uses a MagSafe ring on the commute or a magnetic car mount.

The video is in Japanese. The weight comparison is around 3:00 and the MagSafe tests start around 6:20.

Limitations

MagSafe tests were done with my own accessories, and the drop comment is a single accidental drop onto my desk, not a test. I could not find a current Amazon Japan listing for this exact iPhone 17 Pro Max model, so there is no link for it. Prices are Amazon Japan's at the time of recording.
