Upon delivery I once once tried the switch and it actually came a test tone. Okay, then put into the ground and hoping that the solar cell supplies the part even in bad weather still neatly with energy. And then waited that the mole disappears. In order to better judge, we have made the pile flat. At first I thought the part does not help, because right next to the unit was a new bunch! I thought, Oh great, the mole laughs at the thing .... But after a few weeks it was the mole probably too loud and he has moved into the neighboring garden, where he vigorously now makes a lot of hills. But I was no tip, after the Digger comes back to us :-( Even after a long time everything is still with us molehills free I am happy and grin with a little bit of schadenfreude in the neighboring garden So do not give up hope, be patient...; -)
