### ⭐⭐⭐⭐⭐ Good heart rate monitor
*by M***E on 14 June 2025*

Bought as a gift for my daughter to help monitor her heart rate during workout sessions. It has a strap which fits around her chest and it makes a noise if her heart rate exceeds the rate she sets, based on her cardiologist's advice. She is happy with it.
