PolarH10 Heart Rate Monitor – ANT Plus, Bluetooth - Waterproof HR Sensor with Chest Strap - Built-in memory, Software updates

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.

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.

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.

First time connection to app was a little slow … but that could have been me… it does exactly what it says. Compared to other HRM I have used it is reliable and you can easily change sports / activities. Tracking heart rate is simple but doesn’t give as many feedback features as other HRM….but if you don’t want to over analyse that’s fine, it’s simple and straight forward and effective for the (cheaper) cost.

Perfect, easy to use, easy to set up.

I bought this, plus the strap in July 2022. Initially it worked very well but had the odd data hiccup where the heart rate would drop from say 144 down to 135 for about 30 seconds then restore itself. I thought that was acceptable, not ideal but acceptable.All I’m trying to do is keep an eye on my heart rate and not over do it but also record the average heart rate over the session on the Polar Beat App so I can compare sessions fairly accurately. Recently, say over the past 12 weeks or so, the data drop out has gradually become so stupidly severe the transmitter is totally useless. The problem I think is that a decent quality battery now only lasts about 4-5 30 minute sessions if that. The voltage of a new battery is usually say 3.31 Volts. Once the HRM has been worn a few times, as soon as the voltage drops to about 3.00 Volts, the data recording becomes totally unreliable. I’ve just tried some Duracell Procell batteries and they are producing exactly the same results as the Duracell batteries so I really don’t think there is any issue with the battery. I should also mention that there is plenty of saliva used on the strap to help conductivity.At the moment, I feel it would be far more accurate simply guessing your heart rate. Also, irritatingly, the Beat App sometimes produces a message saying it can’t connect to the monitor because another App is using it. Well, it isn’t and I can’t get rid of the message without unpairing and repairing. That’s a pain in the arse if you’re out and about doing a run and you want to split it and restart. Last night was the final straw because I was using a new battery, without a tee shirt on and the transmitter was about 15 – 18 inches from my phone and the recording was utter rubbish – see picture. Additionally, the cross trainer should pick up the signal and display accordingly but it never displayed at all for the whole session.I’m going to try to contact Polar customer services to try and resolve this and if the situation improves drastically, I’ll amend the review. If it doesn’t, I’ll ask Amazon if I can review with zero stars, add some nice comments about the Polar Support and start investigating Garmin HRMs.

I've had a polar for a long long time. I like the accuracy, reliability in use (zero drops outs or miss reads) and comfort. It fits easily, the opener clasp is simple and you don't really notice it in use. If I had a minor gripe it's that the belts do wear. It's fabric and so the pulling on and off wears around the studs. Wash regularly, dry and put the monitor on and off with care and you'll enjoy the quality and comfort for a little longer! To be honest I'm not sure I'd use anything else, as everything else I've tried had too many compromises or lacked a finishing detail.

I am very pleased with it. Fits very well and feels of very good quality.
