I purchased 2 of these units. When I saw the hardware bag I was overwhelmed, then I read the instructions and looked at the pieces and decided to tackle the assembly. Piece of cake and very clear instructions. 15-20 minutes and I was done with the first on. The second one took even less time. 
Regarding quality, they were sturdy after assembly but the edges weren't consistent in color( where seams meet).
Also, there were a few scratches, but not bad enough to send back, considering that they weren't real wood and I didn't expect perfection.
They are serving their purpose and from a distance look expensive.
Only other thing is that the backs aren't finished and it is noticeable considering that they can't be pushed all the way back against the wall because of base trim.
Overall better than I expected.
