Caretaker Ultra Flex 8-Port Motor Assembly (3-7-5)
Due to Caretaker discontinuing several UltraFlex 1 parts, it is recommended to purchase the upgrading kit that comes with a new motor, rather than buying the 3-7-5 motor.
The PCB board 4-7-5 has also been discontinued, so if your PCB board goes out you would have to purchase the upgrading kit to be able to acquire the new PCB board, that comes with the new style motor.
