Review on Ultimate 3-in-1 Stick On Wallet for Any Phone Case: Spandex, Magnets, Double-Pocket, Finger Strap, and RFID Block – Powerful 3M Sticky + Magnetic (White Marble, 1 Pack) by Brian Rogers

Good; So I liked that it was very sticky and thin. The stretch worked well for the four thin cards I needed, although it seemed like it would loosen up over time. But I just tried it because I really want to use wireless charging (which I've been able to do with the same cards in the past) and it didn't work. Biggest complaint and reason for the two star rating; when i took it out of the case the glue stayed behind and although i finally managed (days of effort) not to make the case sticky. The case was scratched and damaged so I couldn't return it. Good product if you need a permanent solution.
