Structure and quality impression of the car go in order, at the price can no longer be expected.
At the first attempt I have burned 2-3 holes in the lawn, because when filling some fertilizer is rausgerieselt below. After the first few laps I was but as far as the grip, the rest of the lawn is fertilized quite evenly. So best not to make the first attempts on the lawn, but on a path or terrace.
I am satisfied so far, the price-performance is good, the device is okay.
Before that I had looked at the reviews on expensive Gritter, apparently you have to spend a lot more, so you actually receive something better.
