The Polar H10 M-XXL is a chest strap heart rate sensor — a pod on an elastic strap that sends data over Bluetooth, ANT+ or 5 kHz — and it takes first place in this ranking. The listing's own numbers back the position up: a Best Sellers Rank of 1 in Heart Rate Monitors, and 15,930 ratings averaging 4.4 out of 5, with a claimed 400 hours of battery life and a 2 year manufacturer warranty.

Its spec table is where the labels start to drift. The Garmin HRM-200 and the COOSPO chest strap in this guide both carry 'Sensor Type: Optical'; the Polar H10's Sensor Type field reads 'Bluetooth HRM, ANT+', which describes how the thing transmits, not what does the measuring — so the table never actually says that what you put on your chest is a strap. The same table gives the fit as 'Fits 66–95 cm chest', while the first bullet lists XS–S at 62–74 cm and M–XXL at 75–115 cm; 66–95 cm matches neither range stated on the page. Everything here comes from the Amazon listing, not from any test of ours.
