Unfortunately I can not give my Vorrezessenten only partly right, because after initial failures, the device now works correctly. At first I had unfortunately also find the the unit mole our precious little interested, because he burrowed cheerfully to pay attention on without this device. Approximately two weeks I saw his driving further until I decided to test as the unit to move by about 10 meters - and lo and behold - from now on is quiet. For the past six weeks there is no new hill more. I would recommend this unit to anyone whose garden is plagued by moles. If it does not work right away should be more sites with patient testing, but only if the right place is found, it is the unpopular troublemaker going.
