No matter how tight I put the band it continues to fall off several times throughout the day as Im moving my hand. The band attaches to itself but keeps coming apart. Now, Ive lost the band somewhere in my house. The "Find Band" accessory would fix that problem, if the vibration was actually loud enough to hear, which its not. So basically I now how to wait until I somehow find it, if someone doesnt accidentally throw it away or something because who knows were it could be. Overall good bracelet though, it tracks my steps/movement pretty accurately and the sleep data works well; just really unhappy that its so easy to lose and hard to find.
