BitbeltJr Alta 3 Pack (Smaller Width) Blue/Grey Works with Fitbit Alta, Flex, Garmin Vivosmart, Striiv, Amiigo, Disney Magicband (Kid) from Loss

These things are essential. I had one on my Fitbit Charge, and it saved it at least twice. By that, I mean there were at least two times when the Fitbit clasp was completely release, and the only thing keeping my tracker on my write was the Bitbelt.I now have a Fitbit Alta. Alta is a very nice looking unit, but the clasp is even *less* secure than the Charge. There's no way I'd wear my Alta without these belts.I hope they come out with color black for the Alta, because I'll get some. For now, these will do.

Used these on our Magic Bands for Disney World - anyone with a small wrist will need this size because you will make your Magic Band smaller (by taking the sides off). These worked great. Just FYI - my wrist is 5.75". Anything much bigger will need the bigger ones.

I wish I bought this with my first fitbit, then I wouldn't have had to buy a second fitbit.

an absolutely necessary accessory for the Fitbit!
