We bought this to keep our 8 pound Maltese from going back to the spare bedrooms.  So it's keeping him out and I think he likes being able to see what's on the other side.  Installation was easy, especially if you have high baseboards.  You can actually slide the mounting brackets  (on the part that the screen rolls on to) up so they are further up from the floor and you can also move the lower mounting handle on the screen up also (just remove screw, move up and put screw back in). Just be sure to mount it so that the screen rests on the floor.  Is very stable and my little dog can't slip underneath.  Also like that you can lock the screen in the out position with a simple push/slide of a button.
