HRM on screen is grossly inaccurate unless you tighten the band uncomfortably. Double-tapping to begin/end activity is a crap shoot: you just keep tapping until you get the damn thing to start/stop. It's a nice size for a small wrist but I have to wonder if the larger size (with more wrist coverage) might help function and accuracy.
