The assembly instructions weren't as easy to follow as some reviews state and I can see how some people could have difficulty following them. I had to buy a decent electric drill for the assembly and would have struggled to screw the screws in if I hadn't pre-drilled the holes myself, the only pre-drilled holes were the ones for the hinges and padlock fitment. That said it seems sturdy enough and looks great when assembled, as for being waterproof I'll have to wait and see if it survives the scottish summer weather.
