I wish the clasp was like a watch strap. I use my hands a lot and it often gets snagged and falls off. Display hard to see when outside. BP and heart rate seem accurate. Biggest frustration is if I choose not to wear it overnight the BP reading times get all messed up. Should be accurate regardless. My regular pedometer reads about half the daily steps this one does. This is definitely "movements" vs steps. On the whole I like it for the BP especially.
