Having a round lawn sprinkler in our 4 x 9 m grass found a suitable setting that you get the lawn moist and the surrounding area halfway dry, we tried it with this sprinkler. I have to say, we are thrilled! Finally a lawn sprinkler for rectangular, small areas that can be precisely adjusted and quite simple. And as in previous reviews noted: you can also irrigate a 50 cm wide strip. Simply well thought out!
