From the quality of the device is actually fine. Compromises you have to make the filling. Anyone who thinks that unit fully to upload with fertilizers that can see what that is for a flabby matter. If the grass is wet, it is also no longer properly, because then glued the eject construction with damp fertilizer. Dear first to test a level smaller than the package leaflet of many fertilizer manufacturer recommends and it often back and forth, back and forth and so on ... But who thinks to put the thing on a recommended setting of Gardena, should rather with the device run as fast as he can, because otherwise the fuel consumption is 0.5 KG on 3qm. For those who have never used something, rest assured that it is useful. Unless he knows a professional "vonHandAuswurftechnik".
