Sturdy shelf with a nice clean style. We plan to display sports memorabilia on this in our rec room and it's great for that purpose. 
I like the casters, two have locks. Shelf positions are adjustable to pre drilled positions. 
Overall the materials are sturdy but felt and looked just a little cheaper than what I expected at the price point of almost $200, that's why I rated it at 4 stars rather than 5.
Assembly was pretty straightforward with clear directions. Well packaged and arrived without any damage.
