A major difference between the 250cc and 350cc the model is that the 350 has a water flow control. And this regulation you really need in everyday life, so that one is not completely wet, if you want to change the position of the sprinkler short without having to run repeatedly for water Hann to set up and turn off the water. I did this now solved so that I have a lot of separate regulators connected directly to the sprinkler. That's even cheaper overall than the 350s. The regulators can be in between otherwise use but also, if necessary. For a 110sqm garden performance is more than adequate. Whether the manufacturer's instructions to square-performance ratio is right, I doubt it.
