Review on Wannap Magnetic Wireless Car Charger Metal Rings 6pcs: Enhance Apple Magsafe Charging for iPhone 13/12 Cases with 3M Sticker - Grab Yours Now! by Dave Branch

Thought I'd buy 6 magnet rings! I've had this product for about a month and have already burned 3 of them. The adhesion works at best for a few days. After 3-4 days, half of the ring begins to rise from the body. After about a week, the other half will fall off. The problem is that the heat generated during loading weakens the adhesive. The first ring was fitted to a completely new case. The next 2 times the housing was wiped with alcohol before installation. You may be luckier than me, but I would NOT buy this product again. Instead, I opt for a case with a built-in ring.
