Barrier delivered very quickly (overnight), once installed in minutes and a few strokes of screwdrivers (yes side "have to make holes in the walls" to this barrier, unlike some other barriers, make me put "that "4 stars for having tested other kind of barrier-free holes in the walls that I find more convenient). The advantage that is adjustable without extension is a big plus and allows some savings. Opening in 2 directions (ability to block one direction through a cleat comes with). Easy to open with one hand, easy installation if you use the "paper-meter" comes with. I highly recommend.
