I hesitated a lot before making this purchase. After 2 uses, I do not regret it eventually. The device works well, the result of the cut is not too bad. I get what I had with my electric mower without being bothered with the wire. For cons, the recovery tank is pretty small, empty it often. It does not take any stone or gravel in the lawn. The camera looks solid with the exception of particular recycling bin at the fixing. I could mow the May 1 because the device does not make noises, it's a big advantage. This device is to be reserved for small areas suitable for people to make efforts.
