I ordered these for my 5 year old daughter to use with her vivofit junior and they are perfect! It's easy to switch colors and the device stays in place. I like that there is no zipper. My 9 year old daughter has a vivofit jr 2 and can wear these straps too (they fit her a bit but still have wiggle room so she isn't uncomfortable). It was great that you worked for both of them! Highly recommended!
