LOVE this as much as I thought I would!!! I use them to close my baby in or give her freedom while blocking her from other rooms. Have even just used 2 to block her from getting out of a room while I’m doing stuff. For me it’s common sense but as for the suction cups at the bottom, they work best when you clean them and the surface you’re going to stick it to. I haven’t even needed to use all of the panels all together yet but I know I will eventually.
