Pros: this thing is pretty heavy, so I think it’s sturdy. It looks pretty nice and the optional/adjustable interior shelves are a useful feature. Except for the bolts on the bottom shelf, all the hardware is invisible which makes it look a lot nicer. 
Cons: the instructions are a bit unclear. A few times I had to take something apart and fix it because I missed a step. Also, you absolutely need a mallet (or a hammer and a cloth). You can’t get the shelves secure without it. There are two little plastic pegs on either side of each shelf that keep the shelf from swinging too far forwards or backwards. These are so important to the construction of the piece. If these aren’t pounded in completely, they will quickly get ejected and the shelf will no longer be secured.
The quality is par for the course for these types of storage solutions, unfortunately. Overall I think it’s just ok. I’d recommend for furnishing on a budget.
