Glad to have 2 flaps to keep heat / cool in
I just had this installed for me in my new house. It only took my dogs a couple minutes to adapt to the 2 flap door. They have been used to only one flap and perhaps a slightly smaller walk thorough depth. I like the easy door close and the lock as well. I haven't moved in to see how they will use it daily but.....I don't seen any problems. The only thing that seem weaker is the "brush" on the sides of door flaps . They seem to be partially on the inside and partially on the outside each time the flap is open or closed. I don't know if this will present a problem . I was going to have the dogs use it and see what happened. If it is and if it is an issue in having a disrupted seal I will give a call to customer service. Customer service is awesome and I was please that I got a discount when ordering after having adopted a recue dog and the fact that they donate to the shelter ad well. Fantastic!!!!
