I paid $2,000 for my ionic foot bath, because I was so impressed after one session at a friend's house. I was 4 months in wearing a compression garment on my neck and chin (with a 2-inch band over the top of my head) for lymphedema after they removed lots of lymph nodes going up to my jaw, that were calcified from thyroid cancer. My first feeling after the session was of being lighter - and other friends have said that too. Maybe because heavy metals are being drawn out?
On my hour drive back up the mountain after the session, the compression garment was really loose on my neck for the first time since wearing it. Then it got tighter and tighter as the fluid drained from my face. I got great results from the machine, and have seen lots of interesting gunk come out.
I ran it with just water and it did turn colors, but didn't have all the gunk in it.
