Query: Doesn't stay in place!

Any bit of movement, such as taking a walk around the neighborhood, and this band will slowly move from its proper placement (just below the elbow) toward the wrist. By the time I finished my 5 mile walk, I had to put it around my water bottle because it kept ending up flailing around my wrist! No matter how tight I tried to make it (even to the point of nearly cutting off my circulation) it kept sliding down my arm. This product may work for those of you who sit at a desk and use a computer, but don't plan on going anywhere wearing this -- unless of course you think it's a worthy bracelet.
