Input:
At first, I didn't want these because they didn't have the thumb hole that the others did, and I thought they would be shifting around on my arm, and I like things to be secure.  But, I'm pleasantly surprised that they don't shift around on my forearms, nor on my ankles.  At present, I'm very happy with them.  We'll see how long they last.  This is my third set of ankle weights, the first two started leaking their sand.
