COOSPO HW9 Bluetooth 5.0 ANT+ Heart Rate Monitor Armband with HR Zones/Calories Burned, Optical HRM Sensor for Fitness Training/Cycling/Running,Compatible with Peloton,DDP Yoga,Wahoo

Bluetooth heart monitor
Excellent product. Charges quickly with included USB cable. Comfortable on upper arm…. hardly notice it during workouts. Accurate readings and easy to pair with my NordicTrack stationary bike. Also the CoosproRide app works well and heart rate alarms can be set on smart phone. Reasonable price, works well. Recommended.

Easy to use, not sure of results (Last update)
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 perfectlySecond 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.

Good device, good price.
Works with Polar app perfectly, price is reasonable, setup is straightforward, way more comfortable (and reliable) than a chest strap.

works well paired with my bike computer seamlessly

Received the product but was late
