PetSafe Microchip Cat Door

This Door Will Keep Nothing Out

The manual function works just fine, as it is a mechanical mechanism for keeping it open, closed or one-way. However, the microchip sensor function is useless. Though it senses the chip fine, this door relies on magnets to resist an animal pushing it open, should it be locked. This just means that the animal has to push just a bit harder but it doesn't stop anything. I am highly disappointed with this door. I've had problems with raccoons coming in to eat the cat's food. I got this door to stop that. It'll not stop anything. It wouldn't even stop a stiff wind.
