Hi Mark,

Unfortunately, she doesn't remember off the top of her head who made the unit, but will look into it and I'll try to get some word back to you. I do know that she has been happy with the results on her back. The issues she's having are likely due to something that may have happened to the unit or maybe something different in her chemistry? Sorry I can't be of more help at this point. Hope all goes well for you!
