The flap is fine. Dad took about 3 hours fitting it using a jigsaw and screwdrivers and stuff and it looks really cool. I was a bit anxious during the training and it took a few goes to get used to the "clicking" but I have no trouble now. It is such a relief that I do not have to remember a password - dad says the lock is worked by something in my neck but that is way beyond me. It is great not having Tom coming in every night and eating my supper, but the best news is that I am now allowed to sleep in the sitting room at night - much warmer than the kitchen. I would recommend it to my mates but if they had one I couldn't sneak in and eat their food! Cleo
