I want to thank Fisher Wallace for the help I get from their machine. At first I wasn’t taking the sponges out of the electrode caps to soak them which caused skin irritation. Also I was using the same sponges too often. I wrote them, and they told me how to handle it. I read over the section in the instruction manual that mentioned soaking the sponges, silly me. THIS MACHINE REALLY WORKS. It helps me get through the day. “The machine” as I call it really helps.
