Connects to treadmill and phone / iPad at the same time - works a treat.
Polar H10 Heart Rate Sensor This is a marvellous addition to any training regime; I have not used this before and am struck by the versatility of it's options and accuracy of it's readings. I thought it might be irritating to wear however I have soon got used to it and take no notice of it during exercise. I find the feedback informative and helpful and have also discovered that my smart wrist watch-not a Polar product- is generally inaccurate compared to the chest monitor. I am delighted with this chest monitor.
Not cheap, but good quality!
Fits well. Works well. Integrates with multiple apps.
Good piece of equipment, easy to use and set up
The H10 does exactly what it says on the box and does it accurately.
Does what it says, easy to pair up to treadmill.
Works very well.
Simple and easy instructions, connected via Bluetooth to the Polar Beat app without a single issue and immediately showed my HR. Great product. I've yet to test with other apps as I'm not aware of what ones are free (not requiring a subscription to use).
Free with cross trainer and connects straight away. Apple Watch and sensor sometimes disagree but fairly accurate most of the time. Keep it moist for best results.
Great little product
Free item. Links easily with treadmill and phones.
It’s ok maybe a bit flimsy and fiddly to use but does the job

It does what I expected.
Top end product
Got this free with the JTX Sprint 7 treadmill, nice bit of kit, appears to be pretty accurate and a good app to go with it. Happy.
Nothing to complain about here, it works and connects over ANT+ or Bluetooth.
Not yet used.
Came ‘free’ with treadmill
