Great product just what I needed simple easy to use fc16t9 40w I normally wear 7 could wear a 6 in these 5 fit just perfect. fc16t9 40w While the led light indicator plays a very important safety protection role, designers should improve this. fc16t9 40w Im certain that this is deliberate and it may be that it suits other people but my kids were frustrated by it and kept fiddling. I’d highly recommend these. Really frustated and USD 50 poorer. fc16t9 40w He never wants to take it off and wants to wear it all the time! Grrr
