When choosing, we were a bit skeptical, but the practical size of 12 l for our garden of about 300 m² has yet facilitates decision. And it was just right. Also the price. The installation was straightforward. The "Backpack" version is convenient at work, the belts are OK and long enough pressure buildup by pump with practical levers comfortably and effectively. The 4 different nozzles enable targeted distribution of spray in any position. For fully deserved 5 star and clear recommendation.
