The cutting accuracy of the wall pieces made the fit between some walls too tight so assembling unexpectedly required quite a bit of force. Just a bit more accurate cutting of the pieces would have made the assembly much more pleasant in this respect. Deducting a star because of this.
The smallest 12x14x16 inch (measured 30,2cm x 35,6cm x 40,2cm from the assembled product) box does not have nor need the internal cross support but with the 19mm thick plywood walls it is very sturdy. It's held together by 36 black screws in predrilled screw holes and documented to withstand 204kg of weight on top. This size is perfect for my 4 year old son but probably not very useful for adults. It came with one hex wrench and no other tools were required for assembly.
The product didn't smell of anything when I opened the shipping box. Had to wipe some sawdust from the surfaces but that's it. The outer surface had some cosmetic damages to it but on the dark surface not really noticeable in use.
