Just ordered the scarifiers was already there, only the weather did not cooperate. So I had to wait a bit with the first use. Construction was relatively easy up to the collection bag, here was the instruction not clearly understood. As the weather was it started. I have to say all the things that came out of moss and weeds Altschnitt so, was impressive. I think that the collection bag is of sufficient size, since at the relatively light unit will quickly creates an imbalance and it tilts backwards. One just needs to empty frequently. The end result is impressive in any case. Even friends who have the device already borrowed are very satisfied. I for one can recommend without restriction up to an area of about 300-400 square meters, it thus.
