Absolute waste of money 1

I have, despite some bad customer reviews purchased two of these items and probably thought, or rather hoped, that it is with me as those who here to report positives. Have, with the result that the unwanted underground guests not only frightening, but in dirkten within less than a meter 4 to 5 dug new holes. I can only advise in retrospect of the purchase. Together with the batteries that I had to buy for the operation, this was probably one of the most superfluous and annoying issues I had lately and moved me to my very first review to warn others.
