MEDICOOL Pro Power 20K Hand Piece Cord (Old Style)
HOW DO I KNOW IF I HAVE THE OLD OR NEW HANDPIECE?
Start by looking at your original Medicool Pro Power 20K Handpiece. 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. (refer to image for better reference)
If it does not have a line and the cap is shorter, then you have the OLD hand piece.
