Negative Positive
Title: Worked for a week or so, then useless.
Review: I actually hate to write negative reviews, but this one is warranted. The belt and wrist monitor seemed to work great for about two weeks, then the heart rate indicated on the wrist monitor became nonsensical in relation to the activity, i.e., I'm rowing like a mad man for 25 minutes and I have a heart rate of 36 ??? I think I will get new batteries for both belt and monitor -- even though I've had them for about 45 days -- and see if that solves the problem. I'll follow up on this after I do that. I hate to get burned on purchases like this.
Is the review positive or negative?
