Review on POWR LABS Bluetooth Heart Rate Monitor Armband: Optimal Tracking for Polar, Wahoo, and Garmin by David Boone

Excellent product. I use it when I run my Nordictrack X32i (about 20-30 miles a week). It connects a few seconds after I start my run, so there's a little delay, but it works. I hate chest straps so this is absolutely perfect. It is not stated to work with Nordictrack products, but at least it will work with X32i. It has exactly the same readings as my Galaxy Watch 3, so I'm guessing it's pretty accurate. I love the charger and the fact that it's rechargeable. It's rated for 60 hours, but I'll charge it once a week after about 20-30 hours of use. All in all a great product and I would recommend it to anyone looking for a good heart rate monitor with devices to work with.
