Sturdy, Handsome, doggie door. Definitely one of the best on the market at a reasonable price.
I bought the small-medium-tall wall unit - Clear instructions, solid materials and excellent construction make this a great door, I installed it myself in about 4.5 hrs. The only problem a home installer might have is cutting the tunnel as it is a nice heavy gauge sheet metal (fortunately I have a full set of tin snips). The flaps are really well made with three magnets on each one so it provide a great seal. If your dog is timid about going into or under things I would recommend getting the training flap. I made one and it is helping but the Hale one looks like it would be much better.
