5 Stars
The maxseal is on a level of its own. I have never owned or seen a door that provides what the manseal provides to our home. The insulation on this thing is UNBELIEVABLE! It's worth the investment!
-
Superb
This is an excellent door. Quality at its finest. Thick enough flaps to keep the elements out, easy enough for my dog to access easily. I will never get another dog door for as long as I live. Superb!

Smart Buy
I have had this door for over a year now. It has been the best purchase I have made in that year and has already paid for itself in energy savings. It's true what they say, you get what you pay for. Thanks!

They're ggggggrrrrrreeeaat!!!!
What a door. I am so glad I made my stubborn self spend the extra money on this door and not go with a God-awful plastic door. I wouldn't doubt it if this door has already paid for the difference just in energy savings. As Tony the Tiger would say, "They're ggggggrrrrrreeeaat!!!!"

Thank God for this door
This door is a lifesaver! No more broken parts, air leakage, ripped flaps, bugs, rodents, upset pets, anything! I think this door insulates better than the windows in our house. Definitely worth the investment!

Great Wind Breaker
When I got this door I was afraid that with it's large size it would open easily to the wind. Wow was I wrong. It seals great time and time and again and I no longer worry about losing energy because of my pet door. Thanks!

Lifesaver
Thanks to this door, my home no longer looks like windstorm just blew through. My little ball of energy, sometimes referred to as a dog, is able to go in or out at will. This door has been a relieve to me and a lifesaver to my home. Thank you!
