It doesn’t work
Since I bought the door, I have been in contact with Sure Petcare’s support desk.
First, I installed it on the door and tried to assign my pet. It didn’t work, even after they sent a test kit, which was also unsuccessful. Then I removed the door and was able to assign the cat, as the chip was recognised. I installed the door again, and now it does read the cat’s chip.
It has been a disappointment from the start. Well, I’ll give two stars because at least the support desk is responding and trying to help.
