Cycling Heart Monitor

5 out of 5 stars

Cycling Heart Monitor
I was in the market for a new Heart rate monitor for my cycling need. In searching for one on Amazon, I came a cross COOSPO. What attached to me was the pricing and the company name. I came a cross their model HW9. In comparing with a similar spec if I were to stay with Garmin I would paid more than 2x more. I didn't really look into feed back from other buyers but nothing was concerning. It was better price but not dirt cheap. I also liked the design. I was curious too because it was an armband instead of a chest strap. My main use was for cycling. My biggest worry was will it connect with my Garmin 830 computer, but not only did it connect, the setup was seamless. As for the specs and extra features with the heart monitor, I would encourage everyone go to the website and educate yourself to take advantage of the feature. I also wanted to emphasize I felt very comfortable while I was riding in fact I like it better as a armband because it does not soak up my sweat compare to a chest strap. Another plus is the unit comes with an extra strap and a charging cable. Again if anyone wanted to dig deeper in the specs and feature go to the company website. One thing I noticed the strap size is a medium I wasn't aware when I purchased it. It could matter if your arms is bigger. I also bought their cadence sensor BK9C because I wanted one for my trainer. I would rate it a five stars too. I would definitely try out other products this company offers in the future.

Thank you for your feedback

    Color: COOSPO Heart Rate Monitor Armband HW9Verified Purchase

    I just got this yesterday. I set it up using heartool app on my iphone (this is the app recommended by COOSPO) and everything worked right away.
    I'm 75 years old so the rough estimate of max heart rate would be 145. In my youth I was a good runner with a good VO2 uptake so I could usually exceed my theoretical max, so I would even agree my max might go as high as 160.
    I first looked at my phone at the 10 minute mark of my first workout with the COOSPO today and the app said my pulse was 172! I slowed down (didn't think I was working that hard) and finished the workout. When I looked at the summary it said my max heart rate during the workout was 193! So now I have to say it's not accurate. But I'm not going to give up on it. I'll try it for a week or two and if it improves, I'll update my posting. The app is just a receiving tool, the COOSPO does the pulse monitoring, so I assign this result to the device, not the app.
    I had the max bpm warning set for 145 but never got a warning vibration that I could feel but that might be due to the heartool app. And for those that are wondering why I didn't see the dark red LED, I was running in 30 degree weather so the COOSPO was under the clothing.
    I will add that I wore the monitor on the inside of my upper left arm. I'm going to vary between inside upper arm and outside upper arm, and forearm. Maybe one of those positions will make a difference. I'm also going to try to wear it outside my jacket sleeve tomorrow to see if it will still pick up my pulse; that way I can see the LED.
    I really like the device. Simple, comfortable, easy to set up. I really want this to work.
    Follow up: I wore the COOSPO on my forearm today and ran at a slightly slower pace and the device worked perfectly. I did one section where I ran hard enough to force my pulse over the alarm limit and the monitor buzzed 3 times and it was very obvious. My max pulse was 147 and I didn't push any harder so I don't know if it would have gone higher, but for this workout, the COOSPO did everything perfectly
    Second follow up. I've already been contacted by COOSPO offering a refund at first and then again contacting me after my follow up hoping I would continue to be satisfied. Very happy with their communications. I've added a star 🙂
    I'm taking the star back off unfortunately. The device freaked out again this week. I bought a Polar chest monitor to make sure I had good data so I've been wearing both for a few days now. A couple days ago the COOSPO alarm went off a few minutes into the run and it said my pulse was 160. The Polar said my pulse was 119 and I knew from experience and feel that the Polar was correct. I doubt my heart is capable of a pulse of 160. I'll probably ask to return the COOSPO now which is unfortunate. It's very easy to use and I like the alarm.

    Reviewed in Canada on June 17, 2025

    Been using for about a month and a half and seems to be working well. Is accurate. Use it for about 3/4 to 1 hour per day and stays well charged. Just charged when I received and am still running on the second charge. I use it with the Candence app and they pair well. To turn it off sometimes have to take it off so it is not reading my pulse. Once I remove it and hold the on/off button for about 5 seconds it does shut off. Overall happy thus far.
