CooSpoH9Z Herat Rate Monitor Chest Strap,Bluetooth 5.0 ANT+ Heart Rate Monitor,Heart Rate Sensor with Rechargeable Battery,HRM Works with Strava/WahooFitness/Polar Beat Peloton/Zwift/DDP Yoga App

I contacted Coospo and they responded extremely quickly and dealt with my enquiry to my total satisfaction so their Customer Service was excellent for me.The H9Z is my second Coospo HRM and it works first time every time and gives readings exactly the same as my old Garmin HRM so I am confident it is accurately recording my heart rate.Dual bluetooth is useful as I often have two devices connected when I am cycling indoors.The different coloured lights on the front of the monitor, that indicate which heart rate zone you are in, are not useful to me as they cannot be seen under clothing but it is reassuring when you initally put it on to have it light up to show that it is working.Only two weeks into ownership, it appears to be well made so hopefully will last.

I bought this as a lower cost option to the proper Garmin HRM straps. I know these do other clever stuff but I never knew what to do with that information.Paired with the watch without drama and does a reliable job.Fits well.Easy to clean.Recharge is straight forward and lasts for weeks. This works better for me than the fiddley battery replacement on the Garmins.The app is directed at cycling but is good for direct monitoring when doing cross training or treadmill training.You can turn off the LED if you do not want everyone to know your heart rate (and this saves on the battery).My only slight concern is that the case is made of a hard plastic that might be brittle if dropped.

First time used fantastic, secound time did no work!!!Have emailed customer support have had know reply as yet.Currently on Holiday will be returning it when I get back

Smart, comfortable and does the trick. Literally don’t waste your money on Garmin when this little gem does the trick

First one delivered perfect as per usual by Amazon. Sadly it stopped working after a couple of weeks. Sent back but bought another as this may have just been a one off. Time will tell. Update. Previous issue was user error and buyer not reading instructions properly. After getting a replacement I read instructions fully and you have to moisten the sensor with some water before using. Once I did this it works a treat and at half the price of brand name sensors I would highly recommend.

This device connected up in the first attempt but a week later it stopped working - would not turn on even though it seemed to charge fine, - this seems to be a common problem.It's unfortunate as the device offers what I need but just fails to switch on.Returned item via Amazon customer service.

We have two of these and my wife's works great, however the other is intermittent and often won't pickup a signal/switch on even if fully charged

Only had it a few days but so far it's been absolutely brilliant.Simple set up with a no frills app on Android. It beeps as soon as the device is connected to the strap and detects a signal, which easily done by wetting the strap lightly.It works. Every. Single. Time. No drop outs.Also connected straight away to a treadmill in parallel to the phone app.Faultless.I had a Polar H10 previously and both the app and the strap worked either intermittently or not at all.The coloured light on the device is of limited use; it indicates your heart rate zone, which you can set in the app. Unless you're one ponce about shirtless in front of a mirror whilst working out I doubt it will see much use. It might allow running without a receiving watch at push, with a thin shirt.So far the H9Z has lived up to the reviews and recommendations on line and for a fraction of the price of the H10.I couldn't recommend this enough.
