TENS/EMS Unit 20 Snap Tens Unit Electrode Pads Large Premium Replacement Tens Electrodes Reusable up to 25 Times per Electrode Med X Tens

Very poor quality product that left a red welt on my skin where the pads were. I don't have latex allergies as MedX insists is the problem. I even sleep on a latex mattress. These are not made in the USA, these are very cheap, electrodes that are being sold illegally as "FDA approved" when they are not. I will be filing a complaint with Amazon and the FDA about the business that is selling these.

I purchased these as replacements for my Kedsum unit. I put the first two replacement pads on yesterday and they have both failed. I used the Spectra gel but, as you can see in the photo, the gel substance on the pad has completely separated and cannot be used. I'm very disappointed as I was going to reorder but will look for another product.

I use EMS and TENS every day, and have therefore used a lot of different tens and ems electrode pads by now. My conclusion for these is that they are fair quality for the fair price.On first use, they work great and stick well. However, by the second and third use, the stickiness is more faded than normal and the current is noticeably weaker. I’ve gotten thicker (and slightly more expensive) pads in the past, and I think that is the real difference.If you are on a budget, these are the way to go, but if you can squeeze in a few more dollars, you might want a thicker pair.

Horrible experience, my skin broke out in what can only be described as severe burns. This vendor should be prosecuted for distributing poison! Don't buy this garbage and anyone who has had my experience should contact Amazon and FDA and file a complaint as I am going to do. BEWARE very toxic and hazardous product. Wish I could give 5 negative stars!

These replacement TENS pads work well enough but don't adhere as well as the ones that came with the unit or some others I've bought in past. They also seem to have a shorter useful lifespan than other brands, likely due to the adhesive gel. The instructions say to discard them after 20 uses, but I don't think I'll get that many uses out of them.
