Very handy and lightweight device whose capacity for my needs (5 small fruit trees) absolutely sufficient. With one can inflate to muster the entire spray product, re-pumping is not necessary. The adjustability of the Messingspritzdüse is very useful, you can thus control the spray very nicely and adaptation to individual needs very well. Also the cleaning of the unit is simple (Rinse containers well, then fill again with pure water, inflate and 1-2 liters of water by spraying). All in all a highly recommended device.
