    Use it to track my work out activities but I wear the watch all the time. Like the app to download to my phone and view on the internet. Use it to track my hikes and walks at different events. Fun to see where I went during the day.

    We bought this one on sale but would have chosen it anyway. With a GPS and heart monitoring, coupled with the large numbers for aging eyes, it was what we were looking for. We gave it 3 stars instead of 5 because it doesn't always register the heart rate. We have had to re-pair several times. We were pleasantly surprised that we enjoyed the pace readout as much as we do.

    The polar watch is easy to use and does a solid job with the reports you get on polar flow website. Easy to see where you are making progress on your goals

    The watch is great if you work out and want to keep track of miles and calories. Only downfall is it doesn't read your heart rate.

    I researched this item extensively and chose it for what it should have done; however, it would only hold a battery charge for about 36 hours and what good is a 24 hour activity tracker that has to be charged all the time? Then, when it recommended the software be updated, I followed the directions and it completely deleted my profile and couldn't reload it from Polar Flow. I called Polar and they told me that I needed to ship it back because they couldn't reload it and the battery definitely did not hold as it should. Even so,going on two weeks and $15 - out of my pocket - in shipping later, I still am waiting to be able to effectively track my activity! They should be paying me to TEST their product because it did not work as it was advertised! This was NOT the quality I expected from this product or company!

    I should have researched these products before I purchased this over priced watch. Step count is incorrect. Only works with the heart rate thing when it wants to. I would like to return it but not sure if that's posdible.

    Complicated and faulty

    Purchased one of these after reading good reviews. The first one was faulty and would not sync up to the Samsung Galaxy 4G phone. Returned it for another. Second one did sync up but it would only keep track of certain activities / sleep on random days,nothing on other days. It is complicated and takes many hours to get familiar with how everything works. Time is better spent on just working out and not worrying about all these statistics that will not help you lose anything in the end. Just do your work and forget the complications that take time away from eating right and working out. I returned the second one.
