They fit perfectly and can be worn all day. They did offer to send me some refill strips, so in their defense, they do have good customer service. And the extra reflector on the back? Just icing on the cake. Not sure if you can find better or not out there. I found these hangers and they are great for my needs. The style and quality are nice. For this low price, I expected a lot worse. -If you have REALLY wide shoulders, then I wouldnt recommend for you (say if youre more than 19 inches from one shoulder to the other; or if your nipples are more than 9 inches apart (the midpoint of each) -yes, measure that). when you turn it on it goes full volume every time! I know this machine will fail, and it just a matter of time.
