6 Pack of Black Ionic Detox Arrays, High Grade Steel
2 High Grade Steel Arrays.  These will work almost all Ion Detox Units.  They will not work with the Erchonia brand.  Some sellers advertise Stainless Steel which means that should not rust.  This is not the case.  Arrays will turn brown after many uses and eventualy rust but it will not affect the operation of them.  Just rinse off with water and shake dry or use a blow dryer to make them last longer.  Life of the arrays also depends on the quality of the water that is used and how much salt is added to the water.
