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

So the product does what it's supposed to do. Strong adhesive suitable for multiple cards, elastic band or more comfortable hold. The problem is that it's impossible/very awkward to hold the phone with your left hand as the tape runs from the bottom left to the top right (when it's in place and your phone's screen is facing you). If you are right handed this is not a problem as your finger will not be blocked by the band itself. But holding the phone with your left hand makes the armband almost useless to you. The only photo on the list showing someone holding the phone with their left hand is clearly photoshopped and the strap placement is inaccurate.
