    Super responsive and accurate! Compared to my Apple Watch, this dedicated HR monitor seems to have very low latency. The Apple Watch seemed to be a second or two behind, but the readings were very consistent. Overall, this is definitely a great buy!

      Thank you for the great review, Alex! We’re glad to hear you’re getting fast and accurate readings from your heart rate monitor. Consistency and low latency make a big difference, and we’re happy it’s performing well for you. Enjoy your training!
