Title: unreliable
Review: had I reviewed this after the first time I used it, I would've given it glowing marks, but it has not read my heart rate correctly since the first time I used it. I'm using it for interval training, and I haven't seen it budge when my heart rate is noticeably higher (after a sprint, etc). I guess that's why it was only $35...should've splurged for the $100 Nike. My sister hasn't had a problem with hers. What a bummer.
