Rated 5 out of 5 by from Update Review I bought my polar a little over 3 months ago and I love it. I started my weight loss journey back in September 2013 but the second picture is when I started using the Polar for feedback. I love it. Instant gratification. It lets me know when I need to pick up the pace. Even when I need to take in down a notch. I have a long way to go, but polar is an investment in my healthier lifestyle.

Rated 5 out of 5 by from Easy to use and access the features. I bought this 2 months ago to monitor my heart rate and caloric burn during power vinyasa yoga practice. Wow, I knew I could burn a lot of calories in Jazzercise but I had no idea how much I had been burning in yoga practice. Next was to check out how many calories I burn while down hill skiing. Another, WOW! I love my Polar-FT4

Rated 5 out of 5 by from AWESOME!!! I bought this because I needed feedback. I've been doing Weight Watchers for almost 6 months, and was looking for something to kick it up into high gear. I saw that some of my friends were using this, but I was paranoid that the chest strap wouldn't fit, so much that I almost got the men's one to make sure. It fits great, I actually had to make it tighter. It's a great tool to provide feedback, and make you work harder!!!

Rated 5 out of 5 by from Good value for the money I purchased this watch 3.5 months ago and I love it. I am finishing up week 9 of P90X and it is holding up fine. I wash the band once a week in the washing machine. I like to keep track of my heart rate as well as the calories burned during my workout. I am excited because I just learned it can be used for swimming. I will start using it for that when our pool opens. I do agree with other reviews that a stretchy wrist band would be a nice improvement.

Rated 5 out of 5 by from Keeps you motivated! I love this product! I use it for crossfit and despite the high impact activity, I never felt like the chest strap was gonna come undone; although, I wish the watch had an option for a stretchy band cuz I wear wrist wraps when lifting weights, and the watch is too small to wrap around at that point. Otherwise, this keeps me in check with exertion and effort, and I love seeing how much I burn during an hour of crossfit!
