Query: Wow - Great price and very accurate

I am very pleased with this purchase.1) The chest strap is so comfortable you just hardly feel it after a few minutes. Once you figured out the best location, it's easy to get it back into the same place the next time.2) Upper and lower limit alarm is very easy to set. The alarm does not have a vibrate function (hence the low price), but it is loud enough that I can hear it over my treadmill.3) I checked this against my stationary pressure/heart rate machine, and the readings where EXACTLY the same. I tried this 10 times, with various levels of excercise, and it read the exact same value 9 times, with the 10th being only one off (114 vs 113). My stationary is also an Omron.I would still call this an incredible monitor at a much higher price!
