I use electrode gel to get it to work before I build up a sweat.
Downhill or if it dries too much due to chilly temperatures, it stops working.
If I sweat too much, so it gets too wet between the chest sensors, it stops working.
It works 60% of the time on a good day.
Are there any good alternatives to this non-functional product? I think I'll go back to the very first Garmin strap. It's not very comfortable, but it works maybe 80-90% of the time.
