I read the reviews (many of which were negative), and was skeptical of the quality of the product, and how hard it would be to build. To our surprise for under $200 we couldn't have made a better choice. It took us about 3.5 hrs to fully build but that was largely due to building the top part incorrectly (the holes which attach it to the bottom half were on the wrong end), and we came to realize it when it was time to attach the two pieces together. The only other obstacle was lining up the bottom cabinets, but we finally got it. The entire structure is sturdy but it does sway if you move it side to side (not significantly, and expected on mass produced ready to assemble pieces). 

Overall, it looks very nice in our kitchen and the glass portion gives it character. Definitely recommend it if you are looking for some extra storage space.
