Review on 🏃 Waterproof Men's Running Digital Watch with Heart Rate Monitor Chest Strap, Chronograph, Calorie Counter, and Large Display - Black T057A11 by Reggie Kern

I held my wrist close to the chest strap to turn on the HRM. Then I went with him on the wrist. The wrist doesn't seem to be close enough to the chest strap. When I raised my wrist to check for a pulse, it came loose. Did it several times. If I held it right in front of the chest strap, it was fine. SO >>>>>> DO NOT buy this to walk, hike, run. You will lose the HRM signal when your wrist is at your side. May be fine on a bike or trainer if wrist is straight and centered.
