I'd been using the Polar H10 chest HRM since August 2022. It worked fine for the most part, other than a few instances of the battery compartment being wonky and giving inconsistent readings until I fiddled with the flexible contact inside.Well, it finally annoyed me for good recently when it started to freeze on a BPM for several seconds before dropping/rising immediately. It would do this every few seconds and my BPM readings were always wildly off. I tried everything I could think of to remedy this and figured, after reading tons of similar stories online, it was best to just move on finally and buy something new.I grabbed the COOSPO HW9 Optical HRM and have been using this with zero issues so far. Since it uses optical sensors (like a smart watch), there's no need to wet it first or apply electrode gel. You simply place it around your forearm or your upper arm (bicep).It has its own app but I prefer using the Polar Beat app so I can see the nice colorized graph in real time. That's what's cool about the COOSPO HW9, it connects to pretty much any HRM app (including PULSOID if you want to show your HR while streaming online). All I had to do was turn it on, go into Polar Beat, remove the Polar H10 from my paired devices list, and the COOSPO HW9 immediately showed up and I was able to pair it right away.In order to test the accuracy of it, I have used it in conjunction with the continuous HRM feature of my Galaxy Watch 4 as well as testing it by comparing my heart rate with my Galaxy S10+'s HR measuring feature and the COOSPO has been spot-on for me.A cool feature this thing has is that it has an indicator light on it that changes color based on which BPM range you're currently in. It's especially helpful once your heart reaches 180bpm because the light turns red and the armband vibrates a couple times. That's been helpful when I play because it reminds me to focus on breathing and calming down during whatever song I'm playing that has my heart rate getting so high. If you use the Heartool app, you can change the HR alert value to something other than 180bpm.Anyway, just wanted to give this thing a shoutout for anyone looking for their first HRM, a replacement, or an alternative to a chest HRM. This one is pretty comfy to wear, far better than the Polar H10 to me (which would bunch up on my sides and back). I also like that it has an internal battery that you charge with a magnetic charger (it's recommended to charge it by connecting it to a laptop/computer or DC 5V power adapter).

I use this unit as a HRM but also for HRV readings with different Android Apps to check on my stress level response throughout the day.I give it top Marks for comfort, reliability and battery life. The tactile on button and vibration alert makes it easy to turn on / off the unit under a long sleeve shirt.The unit has one minor use case drawback. For some reason the vibration of car and plane travel makes the HRV readings unusable. Verified with multiple HRV apps. Other PPG sensors I have from Sonche do not suffer from these issues. It's a failure in a narrow use case that won't affect most people only HRV needs like myself. HR seems to remain solid. HRV readings are fine at rest.Android Apps: HRV Monitor, Elite HRV, Coherence Plus Heart Rate.

I bike and walk everyday. As I get older and wiser I needed to make sure I was properly zone training so that I don’t get injured. This HR monitor is simple and is accurate, I compared it to my Apple Watch and to a chest monitor and it is the same. Bluetooth works with my Apple Watch so I don’t need to pair to my phone, but you can pair it to your phone. I also pair this to my computer for Zwift and works amazing. I have had it for a month and it’s still holding its charge. I like the way it looks and it’s easier to put on with all my gear on, I don’t have to remove clothes to put on the monitor unlike my chest monitor which used watch batteries. The rechargeable battery is a huge advantage so that I don’t have to swap batteries ever.
