Jo ,
Matrix is about 2 ft x 2ft square and in three stages of 6 inches high.It has
3000 x's the strength of a tens unit. It really kicks me when I take it. But
unfortunately it doesn't work every time.I can feel it really deep in my
pelvic area. Its almost like someone is massaging that sore area. But it
takes some high intensity to reach that area. It goes as high as 90 I let
them put it to 55 today but it didn't hit the right spot. I have a TEns unit
at home and that is like a bee sting compared to Matrix.
