Works perfect
Use to monitor heart rate while cycling. Synced easy with MyWhoosh, Kinetic Fit, Hearttool. Nice stable readout. Allows me to target my aerobic zone. Reading accurate to pulse on blood pressure machine
Works and seems accurate enough
I wish it had a digital display showing heart rate but I connected it to my iPhone and works pretty good. There is a light option that gives some guidance to heart rate brackets you have to set up so that will have to do. I have not compare-tested the rate with another device but seems to be good enough for me. I recommend this HRM
Just as accurate as Polar Verity Sense
First of all, I cannot wear a chest strap because my chest gets chafed and raw. I have tried body glide, duct tape, banaids etc. No luck. My skin is just too sensitive. So I am forced to use an optical hr sensor worn around the bicep. I own a Polar Verity Sense and love it. I have had it for many years and it’s great. The accuracy is excellent and no skin issues. So then why did I buy the Coospo HW9? I bought a new treadmill that has heart rate programs. To use these programs, you need to connect your hr sensor to the treadmill. The hr sensor needs to be at least bluetooth 4.0 to connect. The Polar Verity Sense doesn’t have the necessary bluetooth version to connect. So I wanted to give the Coospo HW9 a try, since it has bluetooth 5.0. It connected to the treadmill instantly. So how accurate is the Coospo HW9 compared to the Polar Verity Sense? I went for a typical run (including varying speeds) wearing both the Polar Verity Sense and the Coospo HW9 at the same time and compared the hr data after completing the run. The results were that both monitors had the exact same average hr and the graphs were nearly identical, maybe a difference of 1 or 2 bpm a couple of times throughout the run. Polar had my max hr for the run at 182, while Coospo had 180. Very close results indeed. I haven’t tried it for any other exercises but for running I would certainly recommend this, as it is comfortable to wear, easy to use and is accurate.
Accurate HRM
More accurate than my garmin watch. Seems just as good, if not better than Our Wahoo fit arm bands. At half the price ð
Very delicate hinges, broken after 3 months of usage
Not durable, was good as long as it worked, now it is useless.
Works for Me
This is easy and convenient to use. Just download the app, charge this unit and press a few keys on the app and off you go. This can connect to 2 to 3 (or more) blutooth devices simultaneously. I simultaneously tried it on Strava on Desktop computer, Bryton Rider 750 bike computer and on the Coospo App. They show the same readings. Very convenient to use on your forearm.Update : September 30, 2024This unit died in less than 1 year. Got in touch with COOSPO and notified them about this concern. This was swiftly addressed and after 2 weeks, the replacement unit have arrived. I prefer this type of HRM as it can connect to 2 devices simultaneously (Strava on my phone and my GPS head unit on my bike). I can now close this issue and see how it holds.
Overall accurate, but reading the first 10 min is often wrong, and stopped working after 10 months
I’ve used the armband for 10 months now on a regular basis. I’ve noted that 3/10 times when I start running, the reading of my HR spikes to my zone 4-5 (150+), although I’m just warming up and actually have my HR is in the 100-120 range. Then it suddenly comes down to my actual HR and then stays mostly accurate for the rest of my run.I like the ability to manually adjust the HR zones, and to set up an alarm (vibration) at a certain HR.The monitor also automatically connects to my treadmill, which is pretty useful.The monitor easily connects to my Garmin Fenix 5x.Battery seems to last long so far.I prefer an armband to a chest strap (more comfortable), although I wished it were more reliable to provide accurate reading at all times.I liked it so far, however now the HR sensor isn’t working anymore. The device connects to both my phone and watch (and i can see its fully charged), however the green light from the HR sensor isn’t flashing… So it’s basically broken by now…
Great heart rate monitor.
Handy little heart rate monitor. This has worked well for me on several setups including my stationary bike. I would have given it 5 stars, but the fabric strap does have some drawbacks (namely cleaning). Overall, the functionality it is perfect. A great substitute for a chest strap.
