DO NOT BUY THIS.  I am no stranger to building these kind of cam-lok furniture pieces. This one is just garbage. All the tolerances are way off. None of the provided dowels fit tight. In fact most just fall right out of the holes provided and almost none of the cam-locks will actually hold in the locked position. Not only are the cam-lock holes the wrong diameter, but also placed in the wrong distance to fully engage the pin.  This piece of *AHEM* furniture and I use that term loosely is not worth $40 let alone $400
