I bought these for my kids (13 and 15 years old) and just under two weeks ago for our new fixtures. We all think they work great. There is no problem with one of them not responding to touch commands, regardless of color. Easy to attach and does not interfere with charging. A few days after owning her, we went for a bike ride. My daughter fell badly and was thrown off the bike. Luckily, she suffered a bloody knee, torn arms, and multiple bruises. It was hard enough to bend her bike's handlebars. Its protective film on the side is quite scratched. That would be her Fitbit, so I'm very happy with the investment. I agree with all the others that they are a bit slippery and need to be removed for cleaning every few days. But for the price and the protection they offer, this is a minor inconvenience. I would say they are 4.7 out of 5.
