big screws for big holes, little screws for little holes. A few reviews have stated the set screws were too short to reach the shank effectively; I didnt experience this with my particular mounts. My feet felt like someone had torched them. There is a light indicator on the headphones that comes on when charging and goes off when charged. We love the way the bottom hoop holds up the train of my daughters wedding dress. 0 adapter for charging. I am one where I don’t like to use smelly synthetic products on my body and this product is really natural smelling and feeling. While pretty at times they could be annoying which is not a problem, just a push of the button and they are off, then another push brings them back. Along with ESWT ( electrolic shock wave therapy) my crocs have been the main reason I’ve been able to regain my health, well being and sanity, and 40lb lighter! this is very wrong.
