Another question for Bob

[Tu_C]

Hi Bob,

I received my M1 yesterday. I’m so happy and excited. Question: the 2x2 coils are flat with no bumps, one side has tiny holes and the other has none, which side faces away from the skin? Thanks for letting me know, Bob. I feel like Christmas is arrived early this year for me now that the M1 is in my hands

The 2x2 coil array is symmetric, a mirror image of itself, and each coil is fixed into position with respect to adjacent coils, so either side can go toward the skin.
