I have the Gardena Irrigation Control System 4040 with 6 valves 1278-20 since the autumn of 2011. Valves I have before the frost period not - as recommended - all developed, but blown out with compressed air. In the spring of a valve was now broken; nevertheless including due to the price-performance ratio 5 points for the valve. I have now expanded to 3 irrigation valves 1278-20; the delivery was super fast and the price was very good relative to the hardware store. Strong buy recommendation for Gardena.
