After much deliberation and reading various reviews I decided to buy this Gritter. Granted, it is not the cheapest, but worth every penny. The assembly is to be managed easily and conveniently within 15 minutes. The plastic parts make a stable and high-quality impression, the steel frame is powder-coated with a soft grip. All screws and washers are galvanized, the inner roll is plastic coated. Everything made a very solid impression! The calibration is easy to perform with the simple, readable manual. About the various settings in the "dosing" can deploy super evenly any seed and fertilizer. A einstelltabell for Wolf fertilizer, grass seed is. Works beautifully. With the hand lever the lower opening can be reliably opened and closed. The large wheels are ideal, even if not quite flat lawns.
