The 4.2pro's have a light blue endbell (should look identical to zipzap motor contact):

while the crappy 4.2's have a white endbell with a small wire clip as the contact (similar to a microsizers motor).
I have only tested the Motorworks motors on bits and not ZZSE. BUT I GUARANTEE THAT THE 4.2PRO'S HAVE MORE TORQUE AND TOP SPEED THAN ANY OTHER MOTOR FOR A ZZSE.
