Ochun Smart Cat Door

The description stated it was microchip compatible, but it only allows you to restrict entry/exit by attaching a tag to your pet's collar. It does not register your pet's microchip.
I am selling it because it did not meet my intended use.
I took it out of the box for a functional check, but it has never been installed.

The shipping origin appears to be China, and it was shipped in a plastic bag, so the box is not in perfect condition. I have listed the item condition as No noticeable scratches or dirt for this reason.
Two collars and two tags were included, and I will be shipping them as well.
You will need to purchase 4 AA batteries separately.

I am selling this item because it did not match my intended use, but the product itself is sound with no issues with the tags.

The following is a description from the web:
