I am using these in a guest bedroom. They are smaller than I expected (not saying they didn’t advertise dimensions correctly) but you know how photos make things look bigger. I’m not sure what purpose the “V” bottom has maybe could store a book or two. They came fully assembled (except the knob) and my 12 granddaughter helped me attach them to the wall. It was a breeze. The drop down shelf, I hope will be perfect, for a drink or resting a cell phone. When not extended the shelf has no purpose in my opinion. My granddaughter thought they were funky and cute.
