I just bought one but I haven't used it enough yet to see if it works well. The NuSkin product that you use with is it very expensive so I almost didn't buy it. I have now found something else that isn't very expensive and will work with the Galvanic Spa. I will use it and also the NuSkin gel with it. I can't give you a link but I can tell you to google search - galvanic spa help and it will bring up the link that I am talking about. It is about the 4th one down entitled Galvanic Spa review - I love the ....... Good luck with finding out more information about it.
