Your Recommendations
I wanted to say that you were so helpful when I called in, not having a clue as to what door to order. You asked me an excellent series of questions then gave me my options. I decided on the MaxSeal Wide Tall. I'm long retired and was never a "handy-lady" around the house, so when I inquired about installation, your suggestion to contact a local contractor and my home improvement store led me to a great individual who did a terriffic job!

Door Works Great...
After speaking with one of your employees, I ordered this door. The install process went smoothly (the directions were easy to follow) and the door is working out great.

I'm glad I called
I was on the website and I couldn't find the same door that I'd ordered from you in the past, so I called you and boy am I glad. Turns out, the door I bought a couple years ago is no longer available so the male I spoke with suggested this door and it's worked out great. Thanks!

It's been one hot summer
I ordered my door from you in the middle of May and installed it right away. The person I spoke with on the phone said this was the most energy efficient door out there, but my thoughts were "A pet door is a pet door." I was wrong. It has been extremely hot this summer and I was worried that I would see a jump in my utility bills because the AC would escape through the pet door and that is not the case at all. This is a fantastic door!

Needed something good & fast
I purchased a doggy door at a local pet store, only to get it home, cut a hole in my door and determined the pet door I bought was poor quality. I hopped on the web and found your site and called right away. The representative I spoke with took the measurements of the hole I had in my door and matched it with the closest size MaxSeal door. She also checked with the shipping warehouse to see how quickly they could get this door to me. It was delivered by the end of the week and I had it installed before the weekend was up. Your service was right quick!

Genius!
Bravo to the manufacturers of the max seal door! It is obvious that a lot of time, common sense, and skill went into the design of this dog door. Also, great customer service at Moore Pet. Thank you

Awesome Door
I live in Canada, so I purchased this door because it was supposed to be great for insulation. My 3 German Shephards fly through this door probably 100 times a day, and the door seals the way its supposed to every time. I couldn't believe it!! I thought for sure I would be buying replacement flaps all the time the way my dogs run at the door full speed, but the flaps have proven to be very durable as well. This is a fantastic dog door.

MaxSeal Single Flap Matches Most Others Dual Flap
I bought this door leading from my 4 seasons room to my garage. From my garage, I have another brand pet door going to the outside. I wasn't sure that a single flap would be enough to keep out a draft between the garage and our porch, but I tried it anyway. Let me tell ya, the MaxSeal's single flap seals tighter than the dual flap on my other dog door. Before next winter, I will be replacing that one with a MaxSeal as well.

Insulation
I was looking for a door that would have some pretty decent insulation, because i like in the CO mountains. I was looking at the Ruff Weather (i think that was the name) because i didnt want to spend a bunch of money. I called and talked to one of the reps and he mentioned this Maxseal thing. I thought about it for a while and decided to spend the extra money and get one. I have been very impressed with the door and so far it has been keeping the cool nights at bay. Thanks.
