Nice set. I wouldn't call assembly complicated, but it does take a couple of hours per unit, especially if you take your time and glue everything. The wood is a bit softer than I had hoped. I got a hairline crack in one piece and a chip in another while assembling. I was able to fill the crack with Minwax wood filler and I'll cover the chip with a similar product. We'll see how it holds up. 
Not a fan of the holes in the bottom after assembly. I filled those too. I used Carnuba wax on the drawer rails and they slide well.
