It's functional but overall quality is quite low even in the cheap temporary furniture category. The way the laminate was applied to the MDF failed to wrap the edges which leads to a comic book outline type appearance. This also misses providing wood color stickers to cover some of the large rotatable fasteners, something common elsewhere in this price point. We had one of the screws with a burr on it, the metal was pretty low grade so I was able to use my fingers to rip the burr off. The metal studs that get installed would also crack the plastic slightly when tightened by hand (I was not over torquing them). In addition, the thin back material is linked together with hard plastic pieces that had the tips a bit damaged during shipment, this also results in a poor/cheap appearance of the back plane and is miserable to assemble. Good idea for cost savings, unfortunately it kinda sucks. Instruction book could be improved to capture points where assembly may go wrong (not too hard to avoid if you are paying attention), and the part numbering stickers need better adhesive as roughly 30% had fallen off the pieces they were labeling. Hinge adjustment for the doors is great. Another positive is that I think the packaging designer actually knew what they were doing, it was packed better than most other furniture we have bought at this price point.
If you are looking for an el-cheapo book shelf that may get beaten up, this will probably do fine. If you are looking for inexpensive furniture that will look okay within a room, you may give it a pass. There are probably other, higher quality, options available in the same price point from wayfair.
