These shelves look so nice on the wall that you could leave them empty and they’d look like wall art! I like them. They are difficult to assemble. But, once you get the hang (pun intended) of it, it’s not bad. I originally ordered 2 sets. Then, I ordered two more. So, now, I’m getting ready to order two 
more! Just be ready to overcome the assembly issue. It’s not that bad and once you get them up you’ll see that the design indeed, does work.
