This unit goes together easily and seems quite sturdy out of the box. The colour and finish (a matt wax type finish) is really nice.  We've used ours to support a 60 litre fish tank, so to be on the safe side I added a block of wood under the cabinet directly under one of the vertical panels (where the door closes against) so I know it's not going to bend under the weight. So far it's been perfect. 
The whole unit is surprisingly lightweight.
