Used it as a wrist band for sleeping
I bought this because I wanted it for sleeping and I have very thin wrists (5 1/2 ") and other bands  I've used for the FitBit One are too big.  This works and is very comfortable and light weight.  When closed with Velcro it still had a big end hanging off.  I just cut it off with a scissor and so far so good.  It got 4 stars instead of 5 because it is difficult to get it into the pocket.  It's much easier to get it out.  But it doesn't fall out, so that's good.  Getting it into the pocket takes some work.
Rating: 4 stars
