AZ race macHINE POS was a direct rip off of Phantom Slip, which is the clutchless version of the CRE/OPM design.

Phantom Slip. works so bad you never knew it was there, except for thr lighter wallet!

Right now, OPM unit is the ONLY unit I've yet to work with. Tom Fowler was a BIG help on my decision years ago when I choose Kaaz clutch style unit since I was a drag racing.
