Doorman No More!
I am so glad I found this door. It was the first one I found large enough to fit my huge Mastiffs through and it seals great as well! The days of me being a doorman on call have come to a end. Thank you again Moorepet!

Just the Right Size
I have had big dogs for years and they always destroyed the smaller, cheap doors so fast. After having this door for a year and having it still look brand new and the pets never being happier I very pleased with my purchase. Thank you!

Better then we could ever imagine
Finally a solid durable door that can handle anythng. The durability of this door is amazing. Our animals love it, they chase each other in and out of the house now. I now have the ability to watch and enjoy rather then keep opening the door for them. Wish i would have orders this years ago. Way to go Moore Pet Supplies a++++++++++++++++++++.

High Quality
I read all of the reviews posted on your site on this door. Not only did it live up to the hype on the site it surpassed it. I have never had a pet door half as good as this one and I would much more to get it back if I ever moved. Thanks!

#1 by far
I know there are alot of pet doors out there, mostly ones that are a waste of money! I took a chance and invested the money in the Maxseal and I have never been so happy with a pet door. This door works so efficiently and has unbelievable insulation. #1 by a long shot!
-
A+ Rating
I give this door an A+ rating! Compared to the doors I have had in the past this door is on a whole different level by itself. No door has compared in insulation, convenience, or durability....not even close! I love this door and will have a Maxseal until I am six feet under!

This is a great door
The Maxseal is definitely the best doggie door i have ever had and i've had doggie doors for over 30 years. It was surprisingly the easiest to install also and my dogs adapted quickly to it. My only regret about ordering this is that i didn't order it sooner! Great door!

Worth every penny
After months of constantly replacing flaps and having cold air leak in through my old Petsafe door I decided it was time to invest in a quality pet door. I did my research and was throughly impressed with this Maxseal door. After making sure they had a return policy I purchased the door and have never been happier. The door seals great and the flap is super durable and does not even show use yet. Thank you MoorePet!
