Urinating cats made unusable our furniture and terrace. Acrid smell and constantly dirty furniture dragged to the nerves. In our research, we came across this device. After careful reading other reviews, we have a past discomfort (it really works?) Ordered this device. It is now for many weeks in use and it works flawlessly! No more stench, clean furniture and would enjoy the terrace. The shortcoming is that the device must be installed in a rain protected area (just a normal connection transformer without water splash protection!) Was at our covered terrace fortunately no problem. One should keep in mind so. Otherwise, we can really recommend the device - it has helped us!
