Review on 📱 Ultimate Phone Card Holder: RFID Wallet Credit Adhesive Cell Case Stick-on Card Holder for Most Smartphones by Michael Glassburn

Adhesion to the product was good but the edges didn't stick, only the middle. So the pages caught a lot of junk. It never fell out of the case, though, so here's the thing. I can't complain about the optics, it was ok and has never changed during use. I think the biggest problem I had was the ring on the back. I stopped being stable after a few weeks of use. It ended up swinging freely like a playground swing, everything dangling and such 😒 As for the stretch factor, I didn't put too much into it, just the important cards: ID and two credit cards. They fit well and definitely wouldn't fall out at any moment. I would rather have it too tight than too loose. I would use it at night when I don't want to take my bag with me, but not on a regular basis as I need the ring to work well for me.
