I bought the heart rate monitor to keep the heartbeat in training a bit in the eye and being able to train in specific areas deliberately. The clock is functioning properly and has all the necessary features that I need as an amateur. Rarely then drop outs (no heart rate display). The criticized "permanent" dropouts, given here in some reviews, so far I could not identify. Only the operation of the heart rate monitor might be a little easier. Sometimes you have to switch back and forth wildly to make the desired setting between different buttons.
