Good in theory... but you really need to have studs to install. My kit was missing anchors for drywall. The piece I tried to install fell down right away. I used the drywall anchors and they just didn't work - this was only for the steps, not even the perch.  The perch I knew needed to go into a stud.  Now I have 2 holes in my wall from the anchors. I've installed plenty of items with wall dryway anchors, but I think this is too much weight to not go into a stud.
