6 Extra Large Butterfly

These replacement pads work great. The adhesive is very sticky - I wore them all day, on a warm day, and they stayed in place! They fit the electrode wires perfectly. Would definitely recommend and reorder.

We have been using this product for many years and it works well and correct placement helps.

These come out very sticky from the first use. They're a good size; I underestimated the width I was looking for, but it still fits well for menstrual cramps or back pain. Keep in mind that these don't plug directly into some EMS/TENS units; they're not the button-on-type clips like EKG machines. I learned this the hard way and had to separately order plug pin adapters to fit these and then plug that into my machine but it works perfectly. The adapters are cheap, if you need to go that route, too.

I love how large the pads are. They’re great for lower back pain or shoulder pain. My only complaint is that I can only use these maybe two times and then they don’t stick very well. Other than that, they’re great. I’d buy again.

these are great and the perfect width. i have had them for several years and they have not worn out

Worked perfectly with my TENS unit.

These are great. They cover a large area,especially the lower back, and shoulders instead of using 4 small ones. And you're able to reuse them. Just save the adhesive clear card they come on. When you're done stick them back on the clear card. Reusable e few times

Absolutely horrible. Does not stick to your body and does not turn up to full strength. I've purchased these before from other sellers and they do actually work when they're not built so cheap.
