    I love my Polar watch! It keeps track of my steps, sleep and inactive time. It syncs nicely to my Samsung phone and is easy to read and track my activity! I have owned 2 other fitness watches prior to this and this one beats them both (Fitbit and garmin)!

    I like this watch a lot. It is easy to use and syncs with several different apps. The only negative is that it occasionally has trouble connecting to the satellites at the start of a run.

    Shape, size, software and interface are great, but after two weeks the watch would not sync. Contacted Polar Customer Service and they did not reply. Returned item to store.

    This watch works great as an activity tracker and the "real" heart rate monitor is great as well.

    The only reason I did not give a five star is because of the size of the watch, it covers my entire wrist! Love it for my workouts!

    I ordered this on Wednesday and estimated delivery was Friday but I came on Saturday. Anyway I opened the package and my product's box was damaged. Although I ordered a new product, not a display or refurbished one, box was damaged. It wasn't because of shipping, it was a display product. BestBuy tried his chance. Then I even didn't touch the box, I had to take it to the store and exchange it with the "NEW" one!

    Covers lots of vital training stats. Could be a bit simpler and easier to use "on the go", but can be gotten used to.

    This watch is great! It's light weight. I wish it had a built in HRM though so you don't have to wear the band

    Not a good product in comparison to other similar products. Way over-priced and POOR interactive design!!!!!!! Incredibly bad product in the category of products in my EXPERIENCE. My serious recommendation is DO NOT purchase at any price until they fix this!
