Polar H10 Heart Rate Sensor – ANT+ & Bluetooth, ECG/EKG Accuracy, HRV Tracking, Waterproof, Machine-Washable Strap, Comfortable Fit, Replaceable Battery, Sports & Gym Compatible

So the H10 is very good heart rate monitor. Works well during exercise, stretching, running, hiking and martial arts - generally fits nicely and snugly on the chest during all physical activity - that you can forget that it is on. Connection with smartphone during recording exercise - it is very well, it can loose connection if you are using other app requiring the GPS access, then you need to refresh the app (polar beat - just refresh) as other wise it will stop working due to some issues with multitasking and sharing processing at the smart phone. Alto it is work well if you use option of the recording the exercise with the H10 heart sensor and download after you finish. IT works well with watch, no problem at all, no loosing signal, very accurate. The software and app is extremely good and user friendly, providing very good analytical data, and information which you need in nice easy to read format. Compared to the Sunnto, and Garmin software - the way how the data is collected and presented was winner for me to choose the Polar chest heart rate H10. As did not have chance to test it in the water as the swimming - can not comment on that. It works well at the rain and storm weather when you are completely soaked tho :) The strap itself is good size with length regulation. Is has some silicon bumps which helps to keep it nice and comfortable in one place, so it not move around during the high activity exercises. It is very easy to change battery - which make this product last very long. Tested it connected to the watch and smartphone at the same time as it support simultaneously twin connection into the two devices at the same time!!! as well as it can work with one device, and on its own, no need to take phone with you - if you click in the app start recording with the sensor rather life recording with the app, then you can just go with the sensor and when you finish just download the information to the phone. So yes I would recommend it.

Great chest strap heart rate monitor, I find this is far better at reliable, artifact free HRV measurement than any of the Garmin straps I have used in the past and much more comfortable too and feels like the strap will last longer. Just be aware of the strap sizes - The S size is for teeny tiny children and wouldn't even come close to fitting round me even though I'm an S t-shirt, so I had to buy the correct strap seperately.

****Review update**** I originally gave this product 3 stars - I was having mixed results with it. I assumed that this HRM was not able to maintain and record bluetooth and 5Ghz "gymlink" connections at the same time. I would switch the app on (polar or wazoo) in my gym. The PRECOR gym kit would show my HR, but when I checked the app, it showed significant drop outs. I RESOLVED this. It transpired that this was a power management issue on my phone, if I was using Spotify/Netflix at the same time, my phone was not running HR tracker apps in the background. My phone is a Huawei P30 Pro - I went to settings>Battery>App Launch and turned off "Manage Automatically" for each fitness app. Now it appears to operate flawlessly. Both for CV and resistance workout. Now - I give this 5 STARS The Polar H10 features a suite of connectivity options as follows; - ANT+ - which is a Garmin product, and I've yet to find a use for it. I own no compatible equipment. - Bluetooth - great - can support 2 devices simultaneously. - 5ghz "gymlink" - which can connect to some gym equipment eg. Precor In the Polar app you can switch each of these off - I guess this would save power. I cant comment on battery life - not used it for long enough but polar app shows it as "FULL" after 8-10 hours training. The strap is not one of the generic ones, has a plastic clip to connect it together, which I hope will hold up. The cheaper ones have a metal clip. The Polar app is more than sufficient for me - provides a number of profiles for different activities. And a good HR readout is provided at the end, and you can easily see the HR zones as you train. Ive also tried it with Strava, MapMyRun, and Wazoo. All with good results. I cant comment on water resistance - others have commented on this, but I do not swim with this on.

So far, it does what it’s supposed to do - measure my HR. It connects to the gym equipment I use so I can see my HR at that moment and the Polar Beats app allows me to view my HR through a workout in the different training zones. 2 frustrations, I can’t allows find a pre-installed workout that matches what I’m actually doing e.g. stairmaster aka mountain climber and the app doesn’t allows sync my workout with Apple Fitness. It can be forced sometimes but you can end up with a double workout….

Product was never working well from the start - now (after 5 months of frustration) it just does not connect to my phone so I can't measure my hear rate when training. Particularly concerning as I am a cardiac patient and need to monitor my heart rate regularly and consistently. To ensure that I stay within a recommended rate by my cardiologist. It was working well for one week and then deteriorated. Now it is so inconsistent I can not trust the device. Polar Support was useless advised me to buy another strap @34 pounds from their website !! As it is not covered by the warranty. I have replaced the battery twice to see if that would fix it and no luck and tried all the advice from support. Considering the price of this unit i would expect higher standards and being Polar you would expect this. Unfortunately I now have to look at alternatives as this is now an expensive piece of tat in my gym bag. In summary I would not recommend anyone to purchase this product - especially if you are a heart patient recovering from surgery.

最初は慣れないと、邪魔でしょうがないです。胸は痛くなるし。でも慣れると、最強です。腕につける、緑LEDのpolarsenseも持ってますが、正確さと応答早さはもう比較にならないですね。電池もボタン電池交換式ですが、びっくりするくらい持ちます。数ヶ月持つでしょこれ。おもしろいのは、胸に固定するベルトの内側に、テカテカした部分があり、それが肌に密着し、心臓の電気信号を拾っているようで、つまり機械の金属部が肌に触れない、冬にも優しい構造です。LED式が嫌で、胸にこういうガジェットつけても気にならない人は、とにかくおすすめします。

Polar is just amazing. Close your eyes and go for this one. For any extreme activity just ditch your watche's monitor and use this one as it gives perfect reading unlike wrist based. Quality of strap is great.looks cool, especially in red .battery life is amazing. Get it at a discount if you can.

perfekt funktion och snabb leverans

This heart rate strap is a real game-changer. The accuracy is insane, way better than any watch sensor. It connects to all my gear without any issues (Bluetooth and ANT+) and is so comfortable I forget I'm even wearing it. Plus, the strap is washable and you can change the battery yourself. If you're looking for a reliable heart rate monitor, just get this one. 10/10, highly recommend

Good product when it works. But has connectivity issues
