Kitletics Review · 8.4 Good
Polar H9 is a heart-rate monitor. Budget Polar ECG chest strap with Bluetooth and ANT+ — simpler sibling to the H10. I'd shortlist it for polar ECG accuracy story at a lower price than H10. The trade-off is fewer simultaneous Bluetooth connections than H10 — Polar H10 is the cleaner compare when that is most of your week. It fits buyers who actually need a heart-rate monitor, not a one-product rotation.
