I purchased mine about 10 years ago; it's very much like this one in the photo below. It has everything you need (electric array, controller, Himalayan salt) except for the plastic dish pan that you'll put the electric array and your feet in. After about 15 minutes in the water, your feet will feel itchy around the ankles. You soak for 20 - 30 minutes; the water will probably have brown sludge floating on top. Wash your feet off in the shower, and pour the water from the soak in the toilet. After using it, you usually sleep like a baby. They say it's so effective at removing toxins, that it even removes drug residue from people who have been addicted (they say one reason people stay addicted is because the residue from the drugs is stored in their extremities & nerve endings with no way to remove it until it's detoxed).

I've never used zeolite; I use food grade diatomaceous earth and have recommended it to everybody that will listen. Amazing stuff!!! Some prefer zeolite.
