u/ATrainer22

I’ve had my whoop mg for about 4 months and have never been able to get the ECG feature to work. Do I need to shave my arm? I’ve tried every tightness on my wrist, different placement on my wrist, different tightness and placement with my fingers… does it work for anyone? They even just sent me a replacement sensor and still getting the same error when the timer gets down to 1 second.. any help is greatly appreciated.
