“fitbit charge 4 band is great! fits the device perfectly and has stayed secure on my wrist since I got it a week ago. clap is slightly bigger than a fitbit original band, and there are two strap holders on the band. the notches that keep them in place are a little shallow but I've kept my fitbit brand strap holder which fits on there as well for extra security. Postage took about a week longer than expected, but would def buy again!”
