He has just two weeks done his service, he was either defective and it is not noticed, or he's no good, I can not necessarily refer to the previous reviews. Anyway fältt repeatedly the shaft around which the sprinkler moved out of his Oeren guide so that a Kreisbewegnung is impossible. Here sticking with entsprechendenm adhesive would be required. My vote in this case 0 stars. My predecessor, in whom I am oriented me when buying met for many years dedicated service. I wanted to stop just a second sprinkler, which his ministry has acknowledged ready.
