An alternative had so forth. After a long search and compare, we decided for this Electronic flap. The cat has been microchipped, which the veterinarian in 3 minutes and for bearable 30, - completed. The installation of the flap was a bit tricky, because the pictures are not very good and the guide could be better in general. With en little common sense but you get it back yet. We have let our new conservatory door consciously build so that the window glass stops approx 30 cm from the bottom end and there is then Plasikplatte. There the flap fits in cleanly. The average small tunnel frame we had, however, reduced by half, which is probably meant for thicker masonry, Did not work without also. The porch with the electronics is really quite wobbly, which would have certainly better solve, but he is unlikely to be heavily loaded, which should hold. The power cable is dimensioned at least long enough for us, we simply set a power extension to the door and hid behind this cat basket.
The programming is designed, if you read carefully, simple, at least for normal operation, it is not difficult to adjust. The chip was programmed fix, but our cat also makes almost anything with what is asked of her. Has warped even when chipping straight face. The annoying beep when you open the door, we have disabled this sounds except the cat eh nobody and störts only. The passage through the door she had known from the old, which we have shown you a couple of times with some treats and now after a week it's habit. We now superior even if we still are to seal with silicone to the door frame of the door in order to get an even higher weather resistance. All in all, we are quite satisfied and can the model to others.
