Hi guys, i thought i bought a os 12tz spec II speed, but the motor i got was a blue head os 12tz 3 port instead, is there alot of difference in the motors?

i am given the opportunity to return it and get my money back as apparently it was a mistake with their distributor misleading them about what kind of motor it is.


should i just keep it as there is minimal differences or should i get my money back?

thanks.
