When she got a nicer, more expensive bike, I decided she needed a lock. It sometimes has static. Even when I tighten the strap. Turns out, they are UNWEARABLE. Very happy customer! 5? tall and 4. Okay great. So needless to say, Im down to one now. Since she?s worn them I don?t think I can return them. They do have some weight to them and arent flimsy or weak which I thought was pretty nice to.
