Referring flaps on responses of Vorrezensenten, it may or may not know that you only know if you have tried it. So I had a choice of many but none of it was promising or guaranteeing. So I have after the neighbor has bought a buzzer and the animals had successfully supplanted me ordered three pieces of it and spread in the garden. While a station for about 700 m² is good, says the manufacturer, but we prefer a more related. Now the question was whether the great success of the neighbors would be established with us. Since I had so set the transmitter in the ground, no more new hill has surfaced. So I'm assuming that the sender does his job. I was also at night, when I stood by the buzzer (every 25 sec for 2 sec) listen, photovoltaics is therefore good enough to ersorgen to the station 24/7 and immediately after installation. The soil is quite heavy and I have therefore also a little taken care of with the setting, but that remains the green top in the bottom, if you relocated the station, I keep with me not probable, perhaps the manufacturer has also done something, would be expected in terms of DIN 9001 and that he reads the reviews times. I find the Summer not annoying, whom the bother but if he in the garden sometimes "chilled" the can also get away for a few hours at the counter under the crown. No Problem. So the evil burrowers were gone and I had left the station are still 4 weeks. Then I reduced from three to one, and the next day the agitators was back. He then made a pile next to the same transmitter again set. I am now eager to see whether he withdraws quickly. Should not happen, I have to dig up the animal. Then the cost of the transmitter sand money "would have been.
Addition:
Now after I had put the two missing channels back into the ground, apparently on holiday BEEN animals came back. Now dig through my garden and no longer serious about the sender. therefore I have this now removed.
The experience I can now conclude definitively as negative and failed.
