Just got my grand rebuild kit in today after super fast shipping and all from Rob. Got my Grand all built up after weeks of not having it and it was bomb. Then on way into work I drop reo on asphalt right on the RM2 and it wont fire. Im sad. RM2 does not screw into 510 correctly so one of them is messed up. Pulling the trigger on another grand but will have to ship this out in the meantime....had to vent to all my people! At least my girl has her mini working like a champ!
