CYCPLUS Heart Rate Monitor Armband,Bluetooth 5.1 ANT+ HR Monitor with HR Zone LED Indicator, IP67 Waterproof, Use for Running Cycling Gym and Other Sports (2025 Upgraded Model)

works very well and for the price I wasn't expecting it to perform as well. Very easy to use, easy to pair, rechargeable battery using USB-C, what's not to like? I've paired it to a SmartSpin2K on an exercise bike using Rouvy. Works great.

Does the job and is super easy to toss onto an arm. I’ve paired this with multiple brand cycling computers, my phone with Strava, and my pc smart trainer.

Communicates fine with my Garmin Edge 840, even when worn on the wrist. I ended up replacing the band to one that attached fit better https://www.amazon.com/dp/B0DPV3W94N?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 that came in a two pack.

Connects easily to my Edge 830 and Wahoo Kickr. Very comfortable, charges quickly and lasts for many hours of riding. Well worth the cost. Time will tell if it lasts more than six months, like my $90 Polar chest strap.

The 1st Cycplus Armband HRM worked fine FOR ONE DAY, then went wonky on me. Amazon replaced right away, and the replacement has worked just fine (2+ weeks now). Paired just fine with my Garmin Edge 1040. I acquired this armband model b/c I started taking a beta-blocker, and that interfered with signals to my traditional chest strap HRM. Battery life seems to be good, I think they promise ~100 hours; I've worn it on a number of 2-3 hour bike rides since getting the replacement, and having it on at home and on walks, too, and still on the original charge. So...giving it 3 stars b/c of the 1st item, but so far 5 stars on the replacement.

Comfortable and works well. The readings seem accurate. It seems to be less susceptible to inaccurate readings in cold conditions.

Much easier than a chest strap and better continuous recording than the typical smartwatch.

Has no instructions for pairing, links to their own apps on their website doesn't work. This product is a scam and not usable.
