My husband started to get frustrated a little toward the end of building this but the cute notes throughout made us chuckle!  It is very heavy and sturdy.  The top does open and close smoothly.  We haven't had it long enough to truly use it but so hard I am pretty happy with it.  The one downfall is the little plugs to cover the holes.  They are too cheap, crack and don't really stay in well so we just stopped trying to put them in.
