There were some minor finishing issues, such as the veneer having clear joins on the sides where the surface jumps a millimeter.  My main issue is that the final screws to secure the legs to the top table would only be comfortable with a power drill.  Without one, I had to screw them in by hand less than an inch from the vertical leg, notably hindering motion, and beyond that they had no guide holes for the final set, so even with particle board it was a struggle to hand screw them all in.  It easily doubled the construction time of each table, causing me to spread construction out over most of a week.  They're acceptable tables now that they're built, but for the price they could've afforded a few extra guide holes for the screw.
