On 09.05.2010 ordered one and get a few days later delivered. Since the reviews be so different, we have for the time being appointed for a 650 m² garden, only one device. I was skeptical, but I have to say the part apparently fulfilled its purpose. Since the operation, there are no hills! About two weeks ago I've seen, however, early in the morning that the mole is still in the garden. I've seen him "overground" race. Still ... he no longer builds hills. I was skeptical also because of our cats. But the two are totally unaware of the part. What the whir of the human ear in terms ... yes, you can hear it. Even from a few meters away in the garden. But you get used to it. A neighbor, two plots of land on, a device from another manufacturer seems to have in operation. His "Surrabstände" are shorter. Since there are no more hill, I ordered me now not a second device. The One met with us his purpose.
