Pump does not conform to technical specifications listed in the pictures .... ie for those who intend to buy: Height of "lifting" 40cm 150cm and not as on the nameplate of the pump in pictures. The pump is about 4x2.5 cm and is not well galliard !!! the solar panel is 11x11cm and it is true that hair cell to be directed along the axis of the sun so that it sends to the max that I live in the southwest .... It remains for me to buy a real !!!!!
