Extender Band for Compatible with Fitbit Inspire 3 2 HR Fitbit Luxe Fitbit Alta HR Fitbit Flex 2 or Garmin Vivosmart 4 Watch Band, Band Extender for Larger Wrist or Ankle Wear (Black)

Good to have when you wear on ankle. Great deal

I just got this yesterday and have used it for the first time today on my walk. It allows me to wear my fitbit inspire 3 on my ankle and it is very accurate. I wear it with the electronic piece next to the inside of my ankle.It is 4 3/8 inches long and just a bit over 1/2 inch wide. I hope this helps as I found the detentions a bit confusing in the item description.

I bought this because I do not wear a tracker on either wrist. I wear a wrist watch there.I used both of these extensions to put by Garmin Vivosmart 4 on my leg just under my knee. It works.I warm weather I move my tracker to my upper arm. For this I need only one extension.Pros1) It does what I want and it seems to be one of very few options for this tracker2) It's cheap3) It is usually comfortableCons1) The loop keepers are troublesome and tend to fall off2) When putting clothes over this they sometimes twist the strap making it less comfortable to wear.

It barely fits my Inspire but I’m diggin’ it. I prefer to wear my watch on my wrist but I still want to track my steps. Ok works well.

These were whiter than they said they were going to be so therefore they would not fit my watch. Waste of my time

does not work with fitbit charge 4 had to return

Excellent. Would use again.

It does extend the band but it is thinner than the regular band which makes holding the end down challenging.
