COOSPO Heart Rate Monitor Armband HW807, Bluetooth 5.0 ANT+ HRM with HR Zone LED Indicator, Tracking Heartbeat HRV for Fitness Training, Work with Peloton/Polar/Wahoo/Strava/DDP Yoga

I Bought this heart tracker after my second Wahoo tracker failed after 12 months. At less than half the price of another Wahoo this unit connected readily with my Garmin and has worked flawlessly. I definitely recommend these if looking for an arm band HR unit.

Great option for Zwift riding. I've been using this weekly for about four months and only charged it once. Measures within two BPM of my Garmin heart rate strap. No complaints. I like the feature that when you approach your threshold, heart rate it vibrates.

The basic heart rate monitor that came with my Bowflex exercise bike failed after two years. I purchased this as a replacement and it has done the job. Comfortable, pairs easily and has better range than the earlier one (no dropped connection). I put a thin piece of black electrical tape over the light: it is bright and it pulses so it's a bit distracting. The light flashes red and vibrates when the battery runs low, which is a feature that I appreciate.

I tried several devices to monitor my heart rate during workouts. This is the first one that actually works. The smart watches don't work. Highly inaccurate and a waste of money if you are using it to monitor your heart rate. I cross checked this device with a finger device during my entire workout while wearing it on my forearm and they both read the same after pairing it with my Iphone. The heartool app works well and paired easily. I would recommend this device for working out

The Coospo HW807 heart rate monitor is wildly inaccurate. It consistently reads 30-40bpm above my actual heart rate, as measured against a calibrated SpO2 pulse meter, as well as a wired EKG used in my physical therapy sessions. At times it will drop instantly from, say, 180bpm to 70bpm in less than 2 seconds (physically impossible), and then jump up again to the false 180bpm. It's all over the place. Instructions were followed to the letter. Tried cleaning the LED sensor glass as well as positioning on different parts of both arms. No change.I reached out to the company, and they did send me a chest strap monitor (H6 model) as a replacement after several back-and-forth emails with the usual try this-and-that suggestions. I haven't tried the chest strap yet as it is too inconvenient for my usage scenario. You need to wet the chest in order for it to work properly (supposedly). Very inconvenient. Seems telling to me that they didn't send another HW807 instead, as they must know that it wouldn't work any differently than the first one.

I had an incredibly hard time determining which heart rate monitors would work with Zwift on my ipad (I’m using a Zwift Ride with the default wahoo kicker as my smart trainer). After hours of reading reviews and help articles I went ahead and took a chance on this relatively inexpensive hrm. My ipad / zwift saw it immediately and the accuracy rivals or beats my apple watch. Zero complaints! Don’t spend $200 for a complex hrm when this is all you need.

It's a very simple heart rate monitor you'll have to pair it with something but it seems to be pretty accurate and it's very light so I highly recommend it if you're interested in tracking your heart rate during exercise

Good value for price. Syncs up perfectly with my Garmin for cycling. Works well 95% of the time. The key issue i seem to be having is that it gets out of calibration 1nce or twice during long rides when i stop for a few minutes and cool down. It will show 80BPM when my Apple watch says 120. Best i can figure, this is due to quick temperature change on my skin. 75% of the time it comes back to accurate after 5 min once i warm back up. But the other 25% i need to power down and then back on. This all said, i have the same issue with all HR monitors in this price range that i have tested. So for the price, i got exactly what i expected. I do wish that these devices would charge with USB-C, instead of custom cords, but again, don't see any other similarly priced devices that will do that (probably very difficult to get USB-C connector into this form factor.
