This set seems to be sturdy (children haven't tested it yet) but the assembly was a little tedious.  I would suggest the manufacturer providing a bit that could be used with a power tool to ease the assembly process.  Hopefully it will stand up to the forthcoming torture the children will throw at this set, we'll see.  If it ends up failing I will try and come back and update this review (not sure if I can at the moment). Hope this helps...
