This is a fabulous doggy door!  We have had the big brand name for many years.  We recently purchased a new home and needed another door.   Instead of paying for the name brand; I decided to look on Amazon to see if there is something comparable for a better price. YES!  This is it - look no further.  The quality is excellent - the only difference is the material.  This one is metal, whereas the other is hard plastic.  The plastic foor flaps are pretty much identical in quality and functionality.  The magnet strip at the bottom to keep it from easily blowing open is very strong.  Whitepartyof4 definitely recommend this.   Love it!
