Worked great til the device died

For about 1 year, this was a GREAT device. I have occasional Afib. But now, all I get is "noise". Ive switched out 2 batteries... no change.

I would expect this device (for about $89) would have worked for at least 5 years, w battery changes.

Expensive crap, now.
