This is not a Mach3 knock off, it's the original Schick Hydro 3 with the Hydro connect connector. It just merely fits on a Mach 3 handle. Bic also produces carts that fit the Mach3 handle. NEITHER OF THESE CARTS MIMIC THE MACH3 CART DESIGN.CVS sells a Mach 3 knock-off called the Torq 3, that I find better than the "real" Mach 3.
