I agree with the negative reviews regarding durability of the transmission. I was thrilled at the beginning about 2 years ago by this sprinkler. The adjustment in width is great. But after about 2 years the gearbox gave up the ghost. Repair impossible - Warranty abgelaufen-- only clack clack but no switching several interior is apparently inferior plastic in use that has no durability. Here Garden should come up with better quality standards. I am very satisfied for years users of other products from the garden Gardena program and have been very disappointed
