I had problems getting my iPhone to fit in the spring-loaded holder. The plastic housing opened up and the spring appeared to be “sprung,” as I couldn’t tighten the holder on the phone. The whole assembly is unwieldy and is frustrating to maneuver.

It uses a USB to be plugged in, which overheats after like 15 minutes tops. Usually less if the light is on full blast. Not optimal for uses such as Nail Technician stuff / longer term projects
