I had a similar device from the same manufacturer. It may be an older
model since it is a small magnet which hangs around the cat's neck.
The unit had to be adjusted to match the local magnetic field and I
found that it required readjustment as battery aged. It bacame a not
uncommon sight to see two angry cats waiting outside the cat flap when
I came home. So I have dismantled it and replaced it with a standard
old fashioned flap. I do, however have problems with invading cats
especially one a big black monster "the great invader".

Anyone have any solutions to this problem? Do more modern flaps work?
