I purchased two of these gates for the top and bottom of my stairs for a six-week visit from my toddler nephews. When putting the gates up, I was disappointed because the directions said that cups "must" be screwed into the walls when using the gate at the top of the stairs because I didn't want to damage my walls for just six weeks of use. I decided to try to install without screwing in the support cups, and it worked great. I checked the stability of the gates daily, and never once in the six weeks did I need to re-tighten them. They were fairly easy to install, though it's a little awkward. The opening in the gate is narrow, but it was only awkward when stepping through the top gate to go down the stairs, though it wasn't a major issue. The latch was easy enough to do one-handed, and my three-year-old nephew couldn't figure out how to get through. I will mention, though, that my friend's daughter, who is 4.5 years old, easily learned to open the gate when fully latched. If I were using them long-term, I might have splurged for nicer-looking gates, but they did the job well for us. My walls were not damaged when I took them down, though there was a faint smudge on the paint, which I could live with.
