## Customer Reviews

### ⭐⭐⭐⭐⭐ This is a top quality and top grade door
        
*by L***S on March 8, 2019*

I had a hard time finding a patio dog door large enough for my 115lb German shepherd to fit through. Every extra large door I bought was so small he had to squeeze through it. Plus they did not seal well enough to keep the cold out. The flap did not stay closed in the wind and would warp. These were pet safe brand which I'll never buy again. This dog door is high quality top grade, I love it! Security boss is the brand to buy!
  

### ⭐⭐⭐⭐⭐ No More Critters
        
*by W***S on November 9, 2017*
