    Very Happy

    We are beyond thrilled with this dog door. When we were measuring and had questions about fit and size we contacted customer service and when I say it was amazing it’s not often you get customer service that is beyond outstanding. Our questions answered, patience as we measured and asked more question and the correct size was ordered. It took a bit for self installation but that is because of the area I wanted it installed but my husband got it done quickly and simply enough. The door matches the screen seamlessly and looks like it has always been part of the enclosure. As for teaching the girls to go in and out. Some grilled chicken and my girls got the concept in less than 30 min.

    I looked at many places to purchase a dog door and no one had the quality I was looking. When I found this website I was happy they had what I wanted but when I actually received my product the workmanship and quality is simply put superb.

    Customer Service is top notch!

    Amazing quality.. amazing customer service. We ordered two doors because we were unsure of the size. Needed some help with returning the unused one and Weston was amazing ! Their products are far superior than the competitors. Flawless for that matter. Both my pups fit through the doggy door without any issues. Really appreciate all their support with my return and their exceptional product. Highly recommend! Customers for life ! Thank you thank you thank you!!

    Great Service anf company

    Order a lanai pet door because they had the best price by far. Shipping was fast. The item had a small issue (due to the manufacturer) The responded quickly to my issue and came up with a great resolution within the same day. I will be using Adeo again and I highly recommend using this small business!

    Nice door, looked like it was meant to be there. Down side, no lock of any kind? For the price I felt like it should have done all functions.

    Patti Fleeger (Evans City, US)
    Didn't get anything but the door so I can't even install it

    Hi Patti,

    Thanks for leaving us a review. As you know per our emails earlier this week, we are sending you the missing screws and instructions right away. We hope you will update your review of the door after you get these parts and can use the door, I know other shoppers would like to know your thoughts after it's installed
