Before the gate we were using a couple of sides from a pen we had and had to continually step over it. (And one of our dogs learned how to jump over it!)  Now, we can open a gate and comfortably walk through!  It was a good price and one of the only ones to cover the distance we needed while still looking subtle. I was unsure based on the description if it would fit in our space and how the extenders worked so I called the manufacturer and they were very helpful and I ended up getting it right the first time. (The adjusters on each side provide 2.5" of flexibility - 5" total.) It fits into the entrance way with pressure only and we have had no trouble with it loosening.  Our dogs are both under 20 pounds each so we have had no trouble with them knocking it free either.  If you have a bigger dog, you would likely want to attach the screw in cups which come with it for stairs to the wall to further secure it.
