Review on COOSPO Bluetooth & ANT+ Heart Rate Monitor Armband - Optical HRM Sensor, Waterproof IP67, Fitness Tracker Armband Compatible with Zwift, Wahoo Fitness, Endomondo, Peloton - Includes One Extra Free Armband by Cheryl Griffin

Having had many Fitbit models and used both Sosche Rhythm+ and Rhythm24, and Rhythm24 actually broke on two attempts at the wristband-monitor connection, I decided to try this HRM. I use the iCardio app which I like a lot. Both Sosche Rhythm+ and 24 iCardio work exceptionally well, both Sosche HRMs were very good except Rhythm+ stopped working after 1 year. The main downside to this CooSpo HRM is that it loses connection when I do any arm movement: battle ropes, breakaway rows, pretty much any strength training exercise. I already have a month that I ordered with the CooSpo bike computer. Haven't used the bike computer yet and it really puts me off sending the HRM back. I do a lot of cross training and tracking heart rate and calories burned are important metrics. So if I lose 3-5 minutes of accurate reading every twenty minutes of three to four 20 minute cycles, I lose a lot of data. I'm really considering returning this item! Update I am very disappointed with this product. Now, after only 6 months of use, the HRM bandage is more hassle than it's worth. It disconnects while driving, sometimes won't connect to the iCardio app and doesn't work when connected. I gave HRM 3 stars for the first time after 1 month. I'm only downgrading to 1 star because I can't give minus stars. I'm completely dissatisfied with this product, even more so than the two worthless Fitbit monitors that are now winning the lottery for used and worthless digital products.
