    After reading many reviews on this I found this to be one of the best watches to track my heart rate, sleep, and steps. I like the fact it can give me a almost pin point reading on my heart rate as I do CrossFit. The only downside is the app, which from the reviews was the con on this product.

    I love the exactness this watch provides. It counts how many calories by steps, then has modes such has jogging, etc. where it includes a strap and heart monitor so it VERY accurately accurately calculates based on your rate with the blue youth heart monitor strapped on your chest.

    I really like this device. It's extremely accurate and allows for elevation changes, which is a big deal when you live in Southern California. The only thing I am not a huge fan of is the heart rate monitor, I would have forgone that if I had thought it out more.

    This watch does it all except for Heart rate in the band. It does HR but only with a blue tooth chest strap. I love the GPS and multiple screens of information.
