Review on Enhanced Monitoring with 3M Red Dot Electrode: Reliable and Efficient by Brandon Woodson

When I first received them in May 2020 they worked perfectly. But after about 4 months they didn't work. The pads were dry to the bone. Obtain a consistently straight ECG waveform. When I hit the pads, the trail goes crazy. The sticker on the box has an expiry date of 09-2021. Yes the glue is pretty strong which I think would hold them in place if someone practiced with them. But tearing it off is uncomfortable, even if the hair has been shaved off before putting it on. However, it's garbage. I will buy a different kind.
