This Review Title is Zero stars. Completely unusable. and the content is: These are far too small for my face. They appear to be made for children. Every time I moved my mouth the bracket moved all over and ends up in your mouth. You spend all your time adjusting it. I bought them to use while working out, but I couldn't even get it to stay put when walking. They are completely unusable. I'd give them zero stars if it were an option..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
