Query: Didn't work for me.

Despite many reviews touting how well this heart rate monitor functions, I could not get it to work for me. The first time I tried it, the monitor was able to find my heart rate but it was far lower than what was possible. After that, I was never able to make a connection between the chest strap and the watch despite trying multiple positions and re-wetting it constantly. When looking for troubleshooting help,I found the directions to be poorly written and unhelpful. I certainly cannot recommend this product. It is the first product that I have ever had to return.
