  1. New Flap Looks Great! 5 Star Review

    Posted by on 17th Jul 2019

    I've had the dog door for years, and the old flap was looking a little worn. Then new one was easy to install and looks great! Thanks!

  2. Good product 4 Star Review

    Posted by on 28th Jun 2019

    Good product, longevity was less than expected but that is my opinion. Had to repair several times and now not even 3 years old and I am changing out the guts. Other than that it works great, a blessing for a pet owner and it keeps out the cold and heat.

  3. Perfect Fit 5 Star Review

    I found this website looking to replace my flex hinge dog door. Couldn't find one until this site. It came extremely fast and was simple to install in the existing door. it fit perfect.

  4. Best dog doors on the market!! 5 Star Review

    Posted by on 27th Apr 2019

    Love this dog door. It’s energy efficient and looks nice. The design of the flap and the products they use to make it. Keeps the flap from warping and it’s self sealing. Wouldn't have any other kind.

  5. Exactly what I needed! 5 Star Review

    The flap replacement was shipped quickly and very easy for installment. I have 3 doors and it was important that I got the door. Besides, it helped keep the other unwanted animals out of the house.

  6. Gr8 Door except it fails over time 4 Star Review

    Posted by on 7th Jul 2018

    Great door but the material between each section of the entry flap fails. We have had our door approximately 3 years and just ordered our 3rd flap replacement. Good parts are available easy to switch out...we have a large Lab very active...and a Pig she pokes her head in when its time for dinner!

  7. Easy replacement 5 Star Review

    Very easy to replace, nice I could fix just the door and not have to replace the whole thing.

  8. Replacement Part Better Than Original! 5 Star Review

    Posted by on 2nd Mar 2018

    The replacement door is a better quality item than the original. The installation was a little more difficult than shown in the instructions. A second set of hands and it was very easy!

  9. Pet door flaps 5 Star Review

    Posted by on 11th Dec 2017

    The flaps were easy to replace. They do a great job of stopping cold air from entering. The hardest part is for the dog to adjust to it.

  10. Now like new, again 5 Star Review

    Posted by on 10th Nov 2017

    The hardest thing about installing the replacement flap was opening the package in which it was shipped. At first the instructions looked daunting, but by following them step by step it went smoothly.
