Have this flap bought because the whole family was not able to program the pre-existing flap Pet Porte and then rush through within just 30 seconds the cat for programming ... This flap has an LCD display and on all operating states are simple and easy to read. For programming it is sufficient if the cat SOMETIME passes once (of course you should pay attention to this neighbor's cat :-) The flap is also gratifying quiet in swing shut - the previous was very loud. The only drawback point are the tiny wood screws with a diameter of 3.5 mm, which go from the inside by the door panel in the outside and then everything will hold together - that's all too thin.
