Title: Excellent Monitoring Device
Review: If you have a heart condition and need to monitor your percent of MHR (Maximum Heart Rate) for an exercise event this is the gadget for you. The wrist component arrived with a dead battery and the manual states that it must be changed by a jeweler in order to not void the warranty. I opened and checked inside to see if there was a plastic strip to be removed to activate the battery and I was not tempted to change it myself so paid the jeweler to do it. I have found this monitor very useful to maintain my heart rate at/below 80-85% MHR which is a medical necessity for me. I have been able to determine when to slow down a bit (just climbed over the railroad tracks), how fast/how long to walk on my non-motorized treadmill and how to set the paramenters on a motorized treadmill so that an exercise event does not wipe me out for the rest of the day.
