I bought the black case. SUPER impressed! It was packaged nicely with a little hammer inside, so no additional tools were needed. I like how I can change up to make different combinations. I can see how I will change it often to create "new" furniture. The only slightly difficult part was setting up the base but I still finished the whole thing under 30 minutes by myself. So easy to set up, but the end result is very sturdy and looks so nice! My favorite part was how you can also turn it into a desk! 
I combined it with their 76*15 shelf as shown in the picture. Definitely considering buying additional to expand the desk.
