The case itself is very well made, with high-quality materials and strong MagSafe.
Since the design is meant to be attached directly to the iPhone, placing m15i close to the phone is unavoidable. With the Questyle stock cable, this setup caused static noise. However, when I switched to a premium OTG cable, the issue disappeared.
Overall, it’s a great case, but the stock cable may not be the best option if you’re sensitive to interference.
The Questyle Magsafe Cover is a perfect fit for building your own Questyle DAP. I combined a Moto G Play 2024, Questyle M15C, and ESR Magsafe adaptive rings. As I do not own any, I can not attest to the magnetic adhesion to a native magsafe device. The adaptive rings provide a tighter fit than a Moto Magsafe case. The M15C fits securely without fear of dropping out. Time will only tell if the leather will stand up to extended use. All in all, better than resorting to double sided tape or glue.
