So out of the 3 clear, rugged amour and the thin fit covers I bought, the easiest to use is the thin fit that snaps on. But it can snap off too....I looked down at my wrist yesterday and it was gone. No workouts or extreme activities, I just drove my car. So I find it in between the seat and door sill. Yes it was snapped on all the way...Just be aware, I still like it best of all as I have casual and formal situations where I like it on and off quickly.
