Ama, you will love it!! I have the F11 which does not squawk because I told it not to. Before I knew what I was doing with the HR training, I'd just love to watch the calories burned number go up. I don't trust it but if I'm out and am at 700 calories and decide I want to go to 1,000, it still ultimately helps.

HR training has made a huge difference. I don't know if there's a book for simple people out there because if there was, I could've used it. I learned a lot by experience and a bit more from my doctor after he did a stress test. It's helped me do greater distance and it has let me know when I'm feeling a bit off and I don't have the mental fortitude just to realize it on my own.

Have fun!!! I still love looking my watch on Monday because it gives me the total calories burned and exercise time from the previous week.
