First, let me say that I love cats and appreciate their feline grace, unless their droppings. Last summer a new feline is located a few houses from mine. Quickly I found that the soft earth beneath the hedge served "crottoir" the cat. So, having tired of cleaning regularly, I tried at first to dissuade the big cat to its neighbor droppings (which were high too ...) in my garden, with granular repellent bought in garden centers ( quite expensive product) which proved unsuccessful. And then, in order to limit costs and after searching the Internet, I concocted my repellent containing black pepper, supposedly very effective against cats. After several sprays on areas selected by the dear cat with this "home" again and again droppings ... The war is declared, so I take extreme measures and decides to implement of places muddy wooden sticks. Only the beast is clever because it was its droppings between the rows of small sticks, that I was increasing at progressively until constitute a true "line Sigfried" in my garden. By having more than enough to see my garden bristling increasingly sticks, I decided to take the plunge trying ultrasonic repellents, in short I did not have anything to lose. After reading the various opinions on the Internet, I make my order, received both devices easy to install and have them installed at "strategic" locations (locations facing the compulsory passage of twink). I positioned the two buttons in the middle of their race, thinking gradually increase later if this positioning was inadequate (for the moment I have not had to do it). By having read against these devices seemed sensitive to moisture (at the battery cover), I crafted in two plastic boxes protection against rain with a front window. To date, with more than a month since these two repellents, I do not see no shit in my garden (verification done daily). To start of installing the units, once the cat was running like crazy overview along my house and fleeing out of the garden, without asking for his, was it the effect of ultrasound? As for the operating life of the batteries, I can not speak objectively for now. By cons, to save, every time I have to work in my garden, I raise the protective housings that I made them, and returns the facade with window to the rear which prevents the detector to go off without ceases. So I waited for writing this review and I can objectively say that to date, there are more cat droppings in my garden, and from my observations I sincerely believe through these repellents that I highly recommend .
