    Very positive

    Review by on Jul 2, 2014

    The service of QC and the speedy delivery of the product was fantastic. I love my MINIDOS pump, it is all installed and running very smoothly. The installation went very good. It really makes the watering, fertilizing, and regulating the quality of the water's PH level so consistent and easy.

    Thank you
