Polar H10 Heart Rate Monitor – ANT Plus, Bluetooth - Waterproof HR Sensor with Chest Strap - Built-in memory, Software updates

Looks to be well built with fast connection and a good price. Will help fitness improve no doubt and is comfortable and works well. Designed to be worn under clothing too. Hopefully lasts a long time.

The item arrived in a nice efficient package and was easily unpacked. Adjusting the strap is very straightforward and, once suitably modified, the strap is comfortable to wear after the initial shock of the cool pads passes.I found pairing the device to both the polar apps and the QZ app I use for my spin bike very straightforward and have had no issues with the device being automatically picked up on subsequent workouts.I bought this primarily for the reliability of the monitoring and open nature of conenction (i.e. being able to easily pair it to third party apps/devices) and I'm happy this has lived up to the promise on both counts. The monitoring element is more accurate than the optical monitor I had in my Pixel watch so I'm happy that my workouts are now being more accurately tracked and heart zone based training is more easily tracked now.The Polar apps themselves seem a bit rudimentary but, as noted, you don't have to use them for anything meaningful besides adjusting device settings and applying updates. That's going to be such an infrequent activity that I'm not counting it against the device.At the sale price of ~£60 this is an easy recommendation to anyone needing an open, accurate HR monitor.

****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 STARSThe 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. PrecorIn 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.

I'm a cardiac arrest survivor, and, two years on from the event I need to get moving again.But safely!I used to cycle a lot and have realised that the flat canal paths near me offer a good gentle environment to return to cycling. However I still need to know that I am in the safe zone for my heart.The Polar H10 came with some great reviews, particularly for accuracy. I didn't want to spend a lot of money on a fitness watch, I wear a classic!Having bought the H10 I downloaded the (free) Polar Beat app to my Android and signed up to the (free) Polar Flow on my Mac. The H10 connects well to the app via Bluetooth so I start the app, cycle, and check the results when home, they are automatically shared to the Polar Flow too so I can see it on my Mac. I use accurate GPS on the phone and the readouts let me run through my journey on a map.It's early days yet but I'm really impressed. The GPS dropped out on one trip but the heart monitor kept reading. I did accidentally delete one of my sessions of Polar Beat, it seems there is no way to recover it which is annoying. However the level of analysis and understanding that can be gleaned from this device is fantastic and on this brief acquaintance I would recommend it highly.We are visiting Paris this week and I typically walk a lot in cities so I will try wearing it for a walk or two.
