Review on Croakies System Eyewear Retainer Regular: Secure Your Glasses with Style! by Brennan Buckley

I've been using it for several years and haven't found a better lock. I highly recommend myself. Please note that they are 14 inches and shorter than many retainers. The main reason I tried them was to adjust the angle of the earpiece. This allows you to tilt them back towards your neck instead of sticking right behind the glasses or tipping them up when the earbud is down. Overall I am very satisfied and would recommend the other two.
