COOSPO H9Z 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

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.

Worked well for around 2 months. Now wont turn on. Waste of money Edit. After leaving a negative review, they contacted me offering a full refund. To which they never bothered giving and when I chased it they just closed the enquiry and ignore all messages. This company is awful!

I thought I'd give this a bash based on the fact that I have been through two garmin HRMs, neither of which lasted more than a year. It connected perfectly first time to my devices, including my Garmin watch, my Garmin Edge as well as to my cycling fitness app (Fulgaz). EDIT: I've had this HRM for 6 months now and it has worked flawlessly, unlike the two garmins before which both never lasted more than 6 months to a year. It;s accurate, workse well with both ANT+ and BT connections. Now just to get it to stop shouting at me when my HR exceeds 180 :) Highly recommended and upgraded to 5 stars I like the fact that it has an LED indicator to show that it's actually working. You're not going to get much out of the different coloured zones unless you train without a shirt, but at least you know it's working. I also like the fact that it beeps when it wakes up and then again when it goes to sleep. I also like that it's recheargable but I can see people losing the charger if not careful. So far so good. Not going to give it 5 stars because I just haven't had it long enough, but first impressions are better that my Garmin HRMs.

Had this for a long while now. Very good. Connects very quickly and the light on the front blinks and it bleeps so you know it's connected. Stays connected too. The rechargeable battery with cradle is great. Lasts quite a long time. So much better than the wahoo. I've been through 3 of those before getting this. They were much more difficult to connect, often became unconnected and the battery rusted from my sweat. All three broke. This is so much better.

This is great. When it works. First one just stopped one day and wouldn’t go again. Got a replacement. Worked perfectly. Then it stopped. Then one day it lit up and worked perfectly again. Then tonight, nothing. No lights, no power. Nothing. Just can’t be relied upon and customer service have ignored messages.

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.

Have real difficulties turning it off. It is supposed to to turn it off itself, and 3 beeps shows it has done this, however maybe 25% of the times I have gone to use the strap it has been out of battery, I assume as it hasn't turned off, or has turned it self back on without me realising. Works well when it has battery though! easy to connect to Apple Watch.

I bought this COOSPO H9Z Heart Rate Monitor on 8 May 2026, and it was delivered the next day on 9 May. I used it exclusively for indoor cycling, and for the first few days it worked normally. Unfortunately, on 14 May it suddenly stopped working. After removing it from charging, it no longer gives any beep, and when I put it on my chest it shows zero signal. None of my devices can detect it anymore — neither via Bluetooth (BLE) nor ANT+. I’ve tried reconnecting, recharging, and resetting, but nothing brings it back to life. Since it completely stopped functioning after less than a week of use, I will now start the return process and send it back to the seller. Very disappointing experience.

Ho aspettato 5 mesi prima di recensire questa fascia cardio perché volevo testarla adeguatamente. La uso pressoché tutti i giorni per almeno un’ora e ho notato che è particolarmente precisa. Si aggancia rapidamente al Garmin e anche all’iPhone (ho un 12 mini). Non ho, per ora, mai dovuto rifare l’associazione tra i device. La luce è molto utile per essere sicuri che il cardiofrequenzimetro sia attivo. A seconda delle zone cardio impostate con l’app dedicata, cambia il colore: questa feature può essere considerata interessante, ma secondo me non è particolarmente utile, a meno che non ci si stia allenando davanti a uno specchio. La batteria, per come uso io la fascia, dura quasi due mesi. La ricarica è veloce, nel giro di un paio di ore arriva al 100%. Con l’app CoospoRide è possibile vedere anche la percentuale di batteria residua. Qui c’è l’unica pecca che ho trovato per ora: credo che il rilevamento del livello di batteria sia ben lontano da essere accurato, visto che scendo molto lentamente nel tempo e, quando è intorno al 50%, poi il cardiofrequenzimetro è di fatto completamente scarico (smette proprio di funzionare). Complessivamente, uno strumento fatto bene con un rapporto qualità/prezzo davvero ottimo.

El pulsómetro funciona perfecto con mi teléfono Samsung Galaxy Ultra 24 y la app de Polar. Me gusta que sea recargable ya que el anterior que compré era de pila y el filamento de contacto de la misma se acabó partiendo por lo que quedó inservible. He preferido invertir un poco más y olvidarme de las pilas. Es el segundo COOSPO que compro, y diría que aparte de recargable funciona más preciso que el anterior. Es un dispositivo muy funcional por un precio que tampoco es enorme como el de otros. Para mí es más que suficiente.

Je l'utilise depuis plusieurs mois, et il fait très bien le job !

Nicht einwandfrei aber trotzdem Super. Das einzige was negativ auffällt, ist die fehlende Gummierung am Brustgurt. Dadurch rutscht der Gurt im hinteren Bereich nach unten, spannt jedoch vorne den Bereich wo der Sensor sitzt. Somit bleibt die Funktion der Pulsmessung ohne weiteres erhalten. Was richtig TOP ist , ist die Konnektivität. Die funktioniert einwandfrei, egal ob eins oder zwei Bluetooth Verbindungen. Den Gurt einfach anfeuchten, Sensor drauf schon geht's los. Bei mir funktioniert die gleichzeitige Verbindung Galaxy S23 Samsung Health und Bosch Purion 200 (E-Bike) einwandfrei. Nach Dauermessung mit Samsung Health von 8 Stunden ist der Akku noch bei ca. 90%. Ladeschale ist sehr praktisch. Eindeutige Weiterempfehlung!

Easy to set-up with Garmin watch
