Incredible insulation
I ordered this door just hoping it would insulating a little better than the plastic model I used to have, and it FAR exceeded my expectations. I can't even tell i have a doggie door in my wall because no air gets in at all! I am very impressed and would recommend this door to anyone.

Top Notch
This is definatley a top notch dog door. From the time I opened the box I could tell that this was a quality dog door. It has a solid aluminum frame plus the flaps are heavy duty and create an awesome seal.

This door is a job-saver
I recently started a new job that requires me to travel approximately 75% of the time. At first, I thought I was going to have to give Brudos away or pay someone to come over several times a day to let him out. Then my neighbor suggested a pet door. I found your website and ordered one up. Now I'm able to keep my job and my best friend.

Tough Flaps
I have a young Komondor that is expected to be at least 32" tall. He is teething and chewing on everything. I must say that the flaps you have on this door are extremely tough. I've had other doors in the past where I've had to replace the flaps at least once a year without the dog chewing on them. With this door, the flaps are holding up great. My wife wishes her shoes were made of the same material as your flaps.

Most Selection
I have looked at all different brands of pet doors and Max Seal definitely has the most options when it comes to sizes, colors, flaps, etc.
