The flat headed screws are softer than baby food, so either find some better ones or be prepared to drill bigger pilot holes. Basically until I went through and used a 5 drill bit to widen the holes there was absolutely no way to get those screws in. They are extremely soft metal so you need to be careful. The long screws for the crossbar were awful and I'm pretty sure I damaged my drill attempting to get them in, since the allan key is not sufficient for getting them all the way in.
You will also need to buy your own screws to mount it to the wall. There's also no spares in case your screws get munted (which they likely will).
I like that it's proper wood rather than mdf. My original intent was actually to build my own but the cost of this came out about the same as buying all the bits from a hardware store. I'm just using it as a little craft table in a spare room, but if you wanted a heavy duty folding table you'd want something with more than one support.
