Best dog door on the market

This is by far the best dog door on the market. The door seals tightly just liked advertised. We liked ours so much we purchased one for our daughter. We had a minor problem after 2 years I e-mailed the company and received an instant response. The problem was taken care of and because this door is so well built it did not cost us anything to fix. I would recommend this door to anyone who wants a well built dog door that is backed by the company that sells it!
