## Description

Review: Great Door! - I "lucked" out with this door as it slipped into the existing sliding door frame which made it very secure. In addition, I added a small 90 degree metal "bracket" which increased security. Only problem I had was with the "T-Locks" that hold the weather proof panel in place.... my 18 pound cat was able to pop the cover off any time day or night! I mentioned the problem to the seller and I was able to get a couple more T-locks! The seller was great to work with and would recommend this seller.
Review: Patio doggie door - I don't like the way it fits. It doesn't fit tight like I expected it to. It is very flimsy. When dogs go in and out several times it loosens it up to the point that it will fall out. It lets cold air in the house. Very unsatisfied with it.
