Title: I really like it, but it does not work for everyone
Review: I bought monitor for my husband, who could not use it because it fluctuated erratically. Monitor works for me, provided I put a lot of water under the straps. It's really useful to know about the "training zones" and use the monitor. Now, I'm able to tailor workout to "achieve the maximum health benefits..." and avoid unhealthy levels of exercise. I very much like the monitor and recommend it, with caveat that it does not work for everyone. Because of latter and the large amounts of water needed under straps, I did not give monitor five stars.
