This SureFlap is even better than the first. It comes in no more irritating drafts, and the sounds of mechanics have become much quieter. We have two cats that constantly pure through the door and go out, and therefore also the service life of (us) nearly four years satisfied.
For us, the flap is one of the best inventions: The chip-recognition functions with absolute reliability, it only come to own cats in the house. All in all 5 stars!
