Product Review

Comfortable to wear activity tracker around your ankle - keep tracks of ALL your steps while exercising (like on a treadmill, or pushing a grocery cart, or ridding a bike, etc).
The band attach a mesh pouch to hold your tracker and that closed with a touch fastener inside, so you don't have to worry about your tracker slipping out any more.
Very soft, light-weight, even you don't notice it's there.
Easy to use with snaps closure and adjust size.
100% man made, very durable.

At present, our ankle band compatible with the following models:

Fitbit Flex, Fitbit Flex 2
Fitbit One
Fitbit Zip

(PS: If you want to track your heart rate, please turn over the tracker in the mesh pouch so that the heart rate monitor faces out, then wear the ankle band backwards, it'll track the heart rate just fine, but you won't be able to read the screen of your track at all.)
