The evaluated by me cat flap came here and order on time and free from Amazon. The workmanship is very good, the stability of these XL cat flap is good to acceptable. The function is also good to very good, because they are not as fast as the previous cat flap closes, it may happen that they sometimes do not include directly, but only after a while. But this is perfectly acceptable ... However, this flap is still much better than anything comparable, what we have looked at in the direction XL cat flap, this is clearly the best and only viable, we have found! As the product is not manufactured in Germany and was apparently developed mainly for the UK, Australia and USA market and their constructional standards when installing the thickness of the door is a little problem! Only up to 26mm thickness of the door leaf are covered directly by the included accessories without drilling the outer part! Four screws are inserted from one side and then cut into the narrow pre-drilled holes of the outer part. From 26 mm bolts are too short! But the manufacturer has God settled Thanks a total of 3 x 4 screws in various lengths. So you have to use the short screws for inside and outside with a thicker door the way. However, you have to drill the outer holes with a drill 3,5-4mm so the screws fit through and you can screw into the wood. In our case, the cat flap came in the summer door of 30mm thickness, and it was also necessary to tunnel socket to cut something, so that the two halves of equipment correctly. The installation took about an hour to complete. You definitely need a drill and suitable drill, to a jig saw to cut a hacksaw around the neck and a Phillips screwdriver. A file for deburring and finishing of the sawed-off piece or coarse sandpaper! If necessary, you can optionally also refer tunnel extension elements that we did not need in this case at the manufacturer! The cat has the new valve initially observed curious and used within a short time from the inside out. From outside to inside, she was initially hesitant, only when my wife rang the door from the inside, Cena took advantage of the opportunity. Since the new valve is very quiet, we sometimes do not know now whether the cat has used it and many times you do not even notice it, if the mint creeps out, or back in the house. We can highly recommend XL cat flap. Cena also are five cats toes!
