I have several hub city couplers including that one. But I have never used it. I plan on changing the shaft over to 1 3/8" and using it then. I have been using the std hub city with the roll pin. I have been having a lot of success with the hub city brand and would highly recommend it. Note the std hub city style is rated for 75 hp, and the one you are looking at is rated for 125hp. Therefore it should last a long time.
