Get the Ion foot spa, from NRG Footspa.
I have several Testimonials including myself. If you want to save money, I can get you one way below retail. What do you want it for? If you want it for specific issues, I cantell you whether it will work for you or not. Arthritus, yes; liver issues, yes. IF you are an alcoholic, do not use this machine. If you are over toxified and i shoes, then definately yes; if you are a soldier with uranium poisoning, definately yes, your rashes will heal up.
