The COOSPO Heart Rate Monitor Chest Strap is the sixth product in this guide. It is a chest strap that broadcasts heart rate over Bluetooth 4.0 and ANT+, pairs with apps from Zwift and Wahoo to Peloton, Komoot and iFIT, and runs alongside GPS watches and gym equipment. It costs £24.79 and holds 4.1 out of 5 across 5,212 ratings.

The listing is where this one gets interesting. Its own bullet points describe the strap as 45 g total; the specification table on the same page lists an item weight of 70 g. That table also gives a display size of 0.96 inches for a product whose only stated outputs are LED indicators and beep tones — a chest strap has no screen to measure. The sensor type is listed as "Optical" as well, on a device most people would assume is a contact strap. Where a spec sheet cannot describe the thing in front of you, the 4.1 rating and its 5,212 ratings are the numbers worth trusting. Everything on this page comes from the Amazon listing, not from any testing we carried out.
