I ordered this HRM from Walmart.com, I ended up returning it to a Walmart store. Here's the review I provided on the website.
1 out of 5
Thinking about ordering it again..., 03/13/2010
Well I ordered this and wore it once while working out. Loved how it connected to the elliptical on it's own and kept track of my heart rate and calorie burn. Calorie burn seemed about the same as it normally is with me just holding on to the handles for it to catch my heart rate. I wore it while sitting on the couch and it seemed like my heart rate was all over the place. Wore it to a Zumba class, and it told me I burn 112 calories in an hour....there's no way that could be right, especially since I was over my heart rate max in less then 10 minutes. I almost want to think mine was defective and order another one...just not sure about doing it. On the plus side it was easily returned.
