Went together without a problem and very very nice desk.  It is exactly what you expect for the price, and that’s not negative, it is Functional and stylish yet a little light duty.￼
It’s a great workspace but don’t put anything on it that moves or is fragile because the desk does shake quite vigorously if you bump it, it’s just not sturdy like you would expect from an executive desk￼.
The drawer rails are sturdy and the drawers work smoothly. The only problem I had during construction was one of the rails stuck and I had to take pliers and bend it a little bit￼.  Again, fully expected at this price range￼
I would give it five stars due to the price range but I’m doing four just because of the wobbliness and I’m someone of a bowl in a china shop so I bump it often.
