One of the cool things I have noticed and more importantly my friends have noticed is that when I pulse my face it literally has a healthy glow to it. My friend made this comment to me today, he said "what did you do? you look really radiant, like glowing." The Sota unit will do this because of the energy imparted by the electromagnetic pulse. They market it officially as "plant growth stimulator" but I think it does some awesome things for body, literally charges it up somehow with energy.
