Review on OWLKELA 10 Pack Metal Plate for Phone Magnet Car Mount Holder - Universal Adhesive Stickers for Magnetic Mounts, Compatible with All Models - Black and Silver (4 Rectangle and 6 Round) by Josh Jeffries

Absolutely terrible. I used the round one and it didn't hold my iPhone XS, I took it off and used the big one because I figured it just didn't have enough room to hook the magnet. This didn't solve the problem. They are very sticky and come off terribly, I usually stick a credit card in and it comes off. Not this one. It was so sticky it bent the metal. I ended up using my husband's tools to get it. I would not recommend it. I've tried adding a magnet to the pathetic case and it didn't work, the phone just slides over the car magnet. They cost $5, that's why I think. I removed the tape from 3 of them to try them out so can't go back now but maybe the next person will save their money.
