### ⭐⭐⭐⭐⭐ 







  
  
    Sturdy
  

*by J***N on Reviewed in the United States on July 5, 2019*

There was no interior cut out template. also there was not an easily discovered install video as well several of the competitors brand. Havingsaid it was a painless install. I am a novice handyman at best and had little trouble. I also have two rambunctious dogs that often hit the dog door either accelerating rapidly if not full throttle. The door (2 weeks) in is securely attached still.  There is no obvious leaking around the seams as to efficiency. We also have had several blowing Tstroms lately. I have not had any trouble with the flaps blowing or leaking. I am very happy with this purchase.

    Great overall
  

*by J***Y on Reviewed in the United States on October 29, 2019*

I really like this doggy door, it is very sturdy and the double flat make it better for the winter. I have two dogs, a yorkie terrier and a mixed chihuahua (bigger than your average  chihuahua). So the yorkie who is younger,  smaller and with a little more energy had no problem with the double flaps, as soon as the door was installed he swished in and out. On the other hand my other do who is a bit over weight, with heart problems and a bit older had a tough time understanding she had to push through both flaps. Seemed they were on the heavy side for her. So we've been trying to teach her with some treats for a few days and as I write this review she's used the doggy door all by herself. Extremely satisfied with it.*added note, bought a second one for another door because I liked it so much. Very strong but easy for my dogs to use.

    Tale (tail) of Two Flaps
  

*by R***Y on Reviewed in the United States on August 18, 2021*

Initially, I purchased this dog door for the dual flaps and aluminum construction, especially the aluminum security door for evening use. However, the flaps quickly succumbed to tearing out at the screw holes as there was no reinforcement on the tops of the flaps and the screws simply were inserted through the plastic. Not a great design. After both doors were damaged in this way, the only way I could repair them was to cut off the damaged part at the top and insert the screws through the shortened flaps. Not ideal as they didn't reach the bottom of the opening, letting heat and insects inside our home. I thought about trying to make something to reinforce the flaps and reinstall them or purchase other types of clear flexible plastic to replace the flaps, but ended up purchasing replacements from Extreme Dog Fence.To my delight, the replacement flaps had metal reinforcement at the top to eliminate the tearing issue. In addition, they included a right angle screwdriver to remove the old Phillips screws and a right angle Allen wrench to install the new Allen head screws. This solved another issue as it was difficult to screw in the old screws with a screwdriver while holding the flap open.Long story short, I'm happy with the replacement flaps and happy the company recognized and rectified the design flaw. The new flaps work great and should last much longer than the originals. I just hate this design issue wasn't anticipated sooner.
