Customer Ratings & Reviews

I've been using Polar products for the last 20 years. I found this device to be easier to carry around and clean. Strongly recommend it.

This is very accurate compared to other tools I have used. Its comfortable and after a few mins you forget your wearing it. Great way to keep track of your workout goals.

I use it everyday and It's very comfortable to use. It pairs easily with Endomondo application and provides fairly accurate hear rate!

Bought this to replace a previous Polar monitor and like this one much better because can link it to my phone with the Polar app.

I prefer this over the watch, because it is compatible with my smartphone, and it gives me a great summary of my workout.

Does what its supposed to do. At first I had a tough time adjusting to the device. The way it wrapped around your chest is not normal with any other device. However after the first or second workout I no longer feel its there. Another thing to remember is don't be afraid to put water on it before putting it on as if you put it on dry it might have difficulty reading heart rate.

Trainers asks that I buy this. I can see why.It is a solid monitor that helps push to heart rate to the burning zone.

Easy to sync with runkeeper on iphone. Tested with old HRM simultaneously and they were surprisingly close in readings.

I've been using it for a few months, no problems at all! Tracks really well and syncs to the Polar app very easily.

I wanted something to wear for longer periods of time so I bought this thinking it would be nice to conceal the monitor as opposed to a watch. It worked great and I installed a free Polar Beat App on my iPhone 6 plus to get the readings. However, after a week of wearing it I decided I didn't like the feeling of the chest strap "slipping" down my chest and it seemed like I was adjusting my bra like a woman. So, I returned it and bought the FitBit Charge HR. The product is great and if I was looking for one just for workouts, I would probably still have it.

I love my H7! My trainer recommended it when my Fitbit stopped working and didn't want to purchase a new watch.

Perfect for calculating your heart rate. Great for seeing how many calories you have burned during a workout!

Very happy with purchase. Bluetooth sensor paired with my F4 works perfect and I bought on sale at Best Buy!

Works like a charm. Pairs with my phone and gym equipment seamlessly and provides an accurate heart rate.

Love this product for a more accurate measurement of calories burned.

Bought this for my wife along with a iWatch and she loves it! More accurate than the FitBit or Garmin.

I got this to pair with my Apple Watch since I do martial arts based HIITs, which means that wrist-based heart rate monitoring is horribly inaccurate. The Polar sensor adds this accuracy to the Apple Watch or your smart phone. I paired it with several apps and works well. I recommend pairing it with the Under Armour Record app as opposed to the Polar app itself. Actually, don't even bother with the Polar app, but the hardware is perfect.

Great product! Works fine and pairs easily with the A300 watch and heart rate monitor, activity tracker.

It works great with both apps, if your intention is to monitor your heart beat rate... Also it works with Health app from iPhone...

If you want to pair with your phone while saving battery power this is the way to go. The strap is comfortable and it works great. Make sure to moisten the strap before use for better results. This uses low energy bluetooth so you do not connect it in the settings menu. You have to download the Polar app to connect it with your phone. You can then use it with other apps. I personally use digifit. I have had to delete and repair a couple of times but it's not a big deal. I price matched for a really good deal and would buy again in a heart beat, no pun intended. Absolutely love it. The fact the apps will sync with my food diary and modify the calories I need for the day is awesome. So much easier than a watch based design you have to manually input the results into you other apps/websites. I love modern technology!
