I have the car for a while now in use we speak of a clear recommendation! In some reviews was to read that the installation was a problem. I can hardly keep track of who is reasonably well versed technically, gets out the! There is nothing in the construction or the quality of the parts and the assembly instructions, which a smooth structure precludes. You can adjust by a pin, if the wheels are rigidly connected or if a wheel drives the shaft and the other just starts to rotate. The latter attitude, I find better, you're in the car just more maneuverable. The reservoir takes up a decent amount of fertilizer. The setting of the ejection amount is quite possible with the scale, some fertilizers have a direct reference to the recommended setting. The parking area is good. Both finer and coarser fertilizer easily metered. I shower the car after use thoroughly and let it dry, thus preventing one corrosion by fertilizer residues and humidity before. He then tucked under the roof of the shed, 3 hooks for now provided there it does not interfere, because some volume it occupies now times and I need him only just twice a year.
