It is so nice and light
I think my Fitbit records steps more accurately on the ankle.  This one is thin and comfy to wear.  Others have said it doesn't hold the Fitbit in the pocket but you have to give it a stretch to make sure it is under both layers.  I wear it in the pool doing exercise and have had no problems.  It is so nice and light, stays on, dries quickly and is comfy to wear.  I would highly recommend to friends.
