This sprinkler cheats at the details of the degree. The maximum range is measured at the center but flattens on the sides from strong, because the Aquazoom. Thus, it is more a circle than a sprinkler oscillating sprinkler at least you can imagine that as a small square with 2 semicircles at the ends. Noteworthy is the Aquazoom Regner a smaller / narrower irrigation area reached as the smallest of Gardena, the Vario 50 Q & E. So if you want to irrigate small areas should pick up the largest model. Paradox, I really write now? Yes, if the Gardena so want ... If you have a weak pump or multiple consumers at the pump, you can expect only half of the irrigated area.
Otherwise there is not much to say it does halt until now their service. We see what happens after the warranty period, I will report it;).
