Very nice product, perfect for my needs

This is a small machine with a powerful punch. Absolutely wonderful on back pain

Better than what originally came with the product

This works great on minor back pain issues and sort of helps on major back pain issues.

UPDATED REVIEW:I can not say enough about the caliber of this seller's Customer Service. I'm blown away by their prompt response and reaching out to me to offer a replacement or refund to ensure I was satisfied. I love supporting small businesses and I want to see them prosper; with this level of Customer Service, they have made me a fan and I will gladly try any of their products in the future. It's important that we help make that happen - especially when a seller goes so far above and beyond to reach out to a customer. I do hope others find these pads more than sufficient for their needs and rest assured, your money is going to someone who truly does care. In my decades of shopping on Amazon (even back when it was just CDs and books), and being a Prime member for probably 6-7 years now, I have NEVER had a seller contact me after a less than stellar review and certainly not with the speed and graciousness of this seller. Please support them if you are able!Original Review:PLUS: No Chemical Odor. CON: Not Very StickyThis is the second set of replacement pads I have ordered since ordering a TENS unit on Amazon a few weeks ago. I love the few pads that came with my unit but when I ordered replacements pads of that same brand, they came with a HORRIBLE chemical smell that gave me a headache while still in the package from yards away. Then I ordered these. I lov the individual packaging (each pair in it's own little bag) and that there was no odor at all. The problem is that they are not very sticky at all. I would say the adhesive is about a third of the strength & quality that came with my unit. Unfortunately, you have to open them and try them to find out they don't stay on well and then you can't return them. I will have to keep looking for another brand.

They come dry,seem to work well w aloe vera gel.not mentioned?

AS Ordered

They are easy to use, and seem to last quite awhile. The company also seems very kind and committed.
