530 Monitoring Foam Electrodes - 30/PK (Pack of 3)

These larger electrodes maintain a better connection for a longer time than smaller electrodes.

This is a superior product, with great adhesion without leaving any residue. Works much better then the red dot brand. Seller was very good at correcting on error in the order, highly recommend purchasing from seller this great product.

That may seem like a stupid thing to say, but I have an ECG monitor and another type of foam electrode would be spotty when it would work and not work. Seems to have good surface contact.

I've been using these for several months. They work well with my Wellue VisualBeat HRM. Some of these didn't cause skin irritations, but some did... So everyday is just a gamble to see if I'll end up with welts, blisters or skin peeling or not.

First of all, these electrodes do work well. I bought them as an alternative to some rather poor ones that shipped with a wearable ECG unit. The adhesive holds tight without getting too messy when removed, gel conductivity is good, and cost per unit was reasonable. A nice feature is the "tab" for removal. If you leave the backing on that tab, it makes for an easier removal. If you take the tab backing off, it provides even more adhesion.All that said, for what it's worth it looks like I may have received counterfeit product. The exterior package looked correct, but the logo on the electrodes is completely different and lacks the EKG trace in the "Medi-Trace" wording. The last batch I had also was on a single sheet rather than having individual backing on each electrode.

This product is great. It doesn't hurt to pull them off and sticks perfectly without the residue.
