I have rated this as a poor product, firstly because putting it together was quite tricky ( we were replacing an old cat flap that any old cat could come through) to a microchip. Our cat has not been able to go out or in on his own as he doesn't like the clicking noise, he's quite timid. There is no digital display, just two buttons which do various different things but you have to work out how many times you need to press them and listen out for beeps. In this day and age of the digital world I was expecting something a little more hi tech and a little less clunky without a big scanning porch! Plus now when we encourage our cat to go out through it (by opening the flap a little) he will go through but the flap doesn't shut behind him as it gets stuck!!! A complete waste of time because now we are back to 'any old cat coming through!'
