I ordered two of these to go alongside my 3 regular leaning tower shelves (which I love and were a snap to put together). The first one of these was like the others - I put it together in 10 minutes flat and it was super easy and perfect. However, I had significant issues with the second one. The screws just would not screw into the nuts, and I ended up stripping a few of them in my efforts to get them in. Eventually, and with some knowledge of how to do this (basically forcing the screws to make their own grooves in the nut) I got them in, but it took a really long time and I was quite frustrated at the end. The other issue with these is that they really should include an L bracket to attach them to the wall for safety. They are not as sturdy as I would like and could be knocked or pulled over quite easily, especially if there are kids or animals around. I really love the way they look and they add so much interest to my otherwise blank canvas. Just beware if you order one that you could get one with the lame screws and nuts.
