Query: Very nice . . .

After about five years of regular use my Polar heart rate monitor gave out. I don't need anything fancy so I decided to go with the Omron after reading the many positive reviews. I'm glad I did and, honestly, it's a better device than my old Polar in just about every way. It's easy to set the time and heart rate parameters. It has a stopwatch feature and the battery in the chest strap is replaceable (not a feature of the Polar as the photo above indicates). Plus, it's just more stylish and makes for a nice general use digital watch. I have one small reservation: the unit does not record average heart rate over the course of a workout. This is a nice feature of more expensive units but not essential. Overall, I am very pleased with this purchase.
