MEDICOOL - Pro Power 20K Hand Piece Cord (New Style)
How do I know if I have the new or old hand piece?
Start by looking at your original Medicool Pro Power 20K Hand piece. At the end of the unit should be a cap connecting to the cable.
If your cap has two lines wrapping around it, you have the NEW hand piece.
If it does not have a line and the cap is shorter, then you have the OLD hand piece. (refer to image for better reference)
