Had only purchased a device to find out if the cats defense with ultrasound and flash also works. It worked immediately - but the mentioned reach ??? Now that currently there is snow, I could understand the basis of the cats traces that the cats zoom dare no closer than 5 m to the device, but it then deal in a bow. To also disable this Dodge, I have for the land of my son, where the lawn is constantly used as a litter box and for my property still 6 devices reordered, which can be installed but only in the spring. If the devices all work as the one I had purchased "the sample", then the problem cats dirt and Markiergestank should be eliminated.
