    Overall, this is a great watch. Has all the features I wanted, however, I noticed that the step counter feature only works if the hand it's on is in motion. If your hand is resting on a handle while moving (ala: cart or stroller), the steps taken are not accurately recorded. In order to record such steps, you have to activate the gps feature - which will drain power. Other than that, it's a great watch.

    This is seriously the best fitness watch a person who trains or works out every day could buy. It's waterproof so you can wear it at all time to constantly be tracking what you're doing. I love it.

    First Polar Watch

    This is my first polar watch. It has many great features making it a great value for the watch. If the heart rate monitor was attached with the watch that would be a plus, hoping that is included in a future Polar. Other than that the watch with the HR makes it a great activity and exercise tracker. It is very accurate and keeps track of your daily activities 24/7. It also allows you to customize exercises to give you more details of your exercises, something you may not find on higher end watches such as the Apple Watch. You can also setup to receive notifications from your smartphone. Great buy and have enjoyed using it for my daily exercises and activities.

    Works great, had some trouble getting the watch to sync with the phone app. Had to delete pairing and repair and has been ever since. The only thing I wish this watch did was help with a training plan!

    Great experience buying on best buy online and picking up at store. This watch is very friendly or easy to use; Gps has a little delay but not considered as a big issue. All others functions are perfect.

    I love this product. Especially the built in gps. The immediate feedback after a run is also a plus. I also keep a close eye on the activity tracker to make sure I reach my goal daily. It will also remind me when I've been sitting too long.

    It's a great product for those who want to monitor your workouts. Yeah, you're not dealing with radial pulse. but the heart rate monitor makes it an accurate reading. The battery life is great. GPS is very accurate, this is when you will see battery life go down. The watch even knows when you're not wearing it. It knows when you're moving; walking, jogging, running, or even laying down. There is a great selection of exercise programs. You will find yours on the application.

    The app, the website, and the heart rate monitor works flawlessly together. I love that I can use the heart rate monitor to transmit my heart rate on all life fitness treadmills and eliptical machines.

    Great HR Monitor

    I saw a few negative reviews about this and how it syncs but has worked flawlessly for me. Syncing is not automatic but works very well. I love the GPS tracking accuracy. The iPhone app provides great detail and works much better than ifit which I used with my training bike. The only issue that I found is if my iPhone is nearby and Bluetooth is on, the heart rate transmitter will not pair with the watch. Turning off the iPhone Bluetooth solves that issue. Once the transmitter pairs with the watch, then you can turn Bluetooth back on the iPhone. Great product and glad that I did not simply replace my HR monitor with the same thing as previous.

    Polar is the standard in sport watches and this product held up to that standard and beyond. Great that the product comes in white, rather than always having to pick black.

    Good Watch Bad Band

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I purchased the watch and used it everyday for 2 months until the clasp on the band broke which was past my time to return the item. I've been searching for replacement parts but Polar has none so now I'll have to take it somewhere for a repair only two months after buying. The watch itself was great for tracking but the clasp broke way too easily.
