Literally just bought one yesterday and 7 minutes into a cardio session, possibly once I was sweating, it just stopped detecting my heart rate lol. I moved it all around and most of the time it still didn’t work or worked for a brief amount of time. If it turned back on, I noticed it would steadily drop when the monitor on the elliptical still had the proper reading.

I called and they recommended making it tighter so I did today and for 11 minutes it worked perfectly and again, turned off once I was sweating lol. Called again and just didn’t get much advice other than changing wrists or using the other band. I can’t go any tighter since it left marks on my wrist today lol and I have it 3 fingers distance up my wrist so I’m assuming these things don’t work well with sweat?? Any one experience this and have any solutions?
