When they tell you that it will stick to itself and not fall off they are accurate, however it will also stick to other metal surfaces as well :) The magnet that it has on it sure does keep it on your wrist I have tried to make it break free, it sill slip lose a little; however it will just get loose but not fall off the magnet will just re attach I don't do extreme stuff with my watch on though. So I cannot attest for that part of it yet :). One thing I don't like about it thought is that when I am typing on my laptop for work it will stick to the surface as it is hybrid metal surface or if on a desk that is metal it will stick to it, or on my truck it will stick to that when my arm is outside of it. That kind of drives me a little batty but all in all I do like the band but not for the price I spent on it that is why I gave it 3 stars. I said I would not recommend this to a friend only because of the cost of it if it was cheaper I would recommend it the color is nice that is why I bought it actually, but I would tell them it sticks to metal surfaces so be aware of that :).
