I read a number of pros and cons about ionic foot baths before I invested in this one. Some people (including doctors) dismiss them out of hand. But I'm convinced they don't necessarily understand how these work. I decided to buy one, after doing my research, and I'm glad I did. And I'm especially glad I bought this one. I noticed that with a number of the foot baths, customers mentioned that they did not come with instructions, odd as that sounds. That is not the case with this one. In fact, there's a laminated sheet telling you everything you need to know, and a pamphlet in addition.One thing important you DO need to know about how ionic foot baths work is included: the color of the water as you use the foot bath is NOT the most important thing, and in fact some of the color comes from the array interacting with the minerals in your water, depending on how much iron, etc., is in your water.The ionizing foot bath works not primarily by removing toxins via your feet, per se; but it stimulates your body to do that for several days after you use the foot bath. What the ionic foot bath does, more specifically, is create negatively-charged electrons in the (salted) water that are absorbed into your body -- in a manner very similar to using an earthing/grounding mat (but more effectively, in my view), or by simply walking barefoot on the earth for extended periods. There's evidence from several studies and other research that this reduces free radicals and inflammation in the body -- which is why most people feel better after using the foot bath.This particular foot bath comes with two arrays (the second is a spare - the arrays are said to last for somewhere between 15-30 uses); a high-sided plastic tub; a cord that plugs into an outlet and then into a circular control panel, into which the array also plugs. The control panel is automatic: it runs for 30 minutes, the amount of time one foot-bath should last. The panel has small lights on it, which come on one at a time, successively, every five minutes -- at which times you're supposed to add an additional few pinches/ half-teaspoon of salt. The salt keeps the array properly doing what it's supposed to do. You also are given a plastic container of sea salt with a lid that both shakes and pours. So there's nothing you have to provide yourself.You get one other item as well: a large roll of big plastic bags. That's so you can slide the plastic tub into a bag and tie it off -- I use a twist tie, but the bag is long enough to tie it on itself -- before you fill it with water. (I use reasonably hot water, which the directions say is OK: choose a temperature that suits your feet, makes you feel good, remembering that it's going to take a half hour, so the water will cool down some during that time.)The roll of plastic bags and suggestion that the tub be put into a provided plastic bag is a little stroke of genius: the water gets pretty gunky with both minerals and some toxins. So when you're done, instead of having to clean the tub out, you can just throw your tubful of water into a toilet and flush it away, then take the bag off the tub and throw the bag away, and there's no additional cleaning you need to do, other than rinsing off the array with clean tap water.This particular foot bath works very well. It's automatic and needs no adjusting: just turn fill it, add some salt, plug it in, put the array in the water, put your feet in, turn it on and relax. It includes absolutely everything you need -- including the instructions that others leave out!
