Review on Alban RFID Blocking Cell Phone Wallet with Finger Strap - Stick-on Credit Card Holder, 2 Pack, Black (Right Hand) by Patrick Hamilton

Used on the back of the Lifeproof Nüüd iPhone 8 case Works well. Holds cards better than those that insert cards horizontally. I haven't tested the RFID protection, but let's assume it works. The elastic could be more vertical at a steeper angle for better grip. The elastic band could have been made from a more durable material. Cuticles and fingernails stick to the belt material. (Not unusual for one of these cardholders). For right-handed users, it is recommended to place the phone as close as possible to the left edge of the back panel for better grip. *Does not work at close range for left-handers or people using left-handed calls.*
