My own experience with this product says it all: 1) Since the switch looks good and Kärcher is a brand name, so I thought to make a mistake. Initially the unit was going well, that is. after the time set in each case it stopped the water supply to the sprinkler. After about two weeks, the following malfunction showed: after setting up to full 120 minutes remained the internal clock at 30 minutes hang! The effect was that the water supply almost ran all night, instead of stopping after two hours. 2) After my complaint sent me Kärcher very quick and unbureaucratic a new one as a replacement to. So far so good. But the new specimen surpassed its predecessor by classes: in the first night when I wanted to water the lawn for two hours, the internal movement was again hanging in about 30 minutes, resulting in a permanent rain. Conclusion: such a switch is just a bad joke. When this product needs a permanent human Übwewachung its function, then it is unnecessary because completely unreliable.
