Polar H9 Review
The Polar H9 is a well-priced, accurate heart rate monitor that might lack some of the extras included on Polar’s H10 monitor, but delivers where it matters for less money. It offers accurate heart rate data across activities, is comfortable to wear, and has good battery life.
The Best Heart Rate Monitors We've Tested for 2026
Our top pick, the Polar H9, offers all the basic features you want at an affordable price and feels comfortable to wear. The entry-level Polar H9 is the best heart rate monitor for anyone with basic needs, with a wide range of compatibility and an excellent companion app.
The Polar Vantage M3 has premium guts in a mid-range package — with one key flaw
The Polar Vantage M3 is quite reliable for GPS, but a little less reliable for heart rate accuracy in some cases. Still, the mid-range M3 is already making the flagship V3 look a little overpriced by offering the same experience for less.
Headquarters and manufacturing are recorded separately, because they are often different places: a brand headquartered in one country frequently manufactures in another. Tabarnam lists what the catalog holds and marks the rest unknown. Entries come from public sources and may be incomplete or out of date — production moves.
