This bookshelf serves well for what it was intended (holding my books). It is a little flimsy and the bottom shelf had the "groove" made on the wrong side of the shelf (meaning the bottom shelf is showing the white side, when all the others are showing the blue side). It was really easy to assemble. I was able to build it by myself, with a screwdriver and the instructions provided. It took me 40 mins. 
Overall, it serves its purpose, does not occupy a lot of space and it looks good.
