Review on 📱 Highly Convenient Car Seat Belt or Backpack Phone Holster with Adjustable Size for Universal Fit of iPhones, Samsungs, and Smartphones by Patricia Davis

Interesting design, moves and locks at any height along the seat belt. I was able to easily assemble and customize it for my iphone 7. On my first call, I couldn't hear anything even when I brought it close to my ear and the speaker was on, so I noticed the phone was upside down at the bottom of the speaker. down, not up, toward the mouth and ear. So you need to place it with the speaker facing up. Simple but clever idea! Works great for me!
