I purchased two of these, one for my office and one for my utility room. The first one took me some time to assemble (the instructions are a little vague) so a few zip ties were needed. Now the second one took about thirty minutes and looks great. Both however are very nice and sturdy. They were a prefect size for what I needed. The black clips are a bit challenging, but put together correctly....then it's not too bad. I also put both of these shelves together by myself. I give it four stars only because of the instructions not the product. 5 stars on the shelf itself.
