Elastic and colors are great. Exactly what I was looking for. But 2 of the 3 (5 total) I tried WILL NOT stay attached to my Charge 3. One end of the strap stays attached and the other end just falls off the Fitbit after a few uses. Looks like a bad batch of these ends. There's just nothing to snag about the Fitbits connections. I was lucky, I understood what happened, so I didn't lose Charge 3.
