Installation was simple, only requiring two screws to mount the motor unit to the side of the barbeque. Use is also simple, requiring the insertion of the end of the spit into the motor unit and laying the other end in the provided slots. Operation is smooth and uniform. There are only two things to remember and maybe redesign. First the two grill plates must be removed for the rotisserie to operate. Second the small rack above the grill plates is sometimes to close to the meat being cooked. Maybe change it so it can be raised up vertically during the rotisserie operation.
