An excellent storage box. All the sides, top and bottom are made of good solid resin. The sturdiest Ive seen and following the heavy rain over the last two days I can say its waterproof. It took around 90 mins to assemble with no issues. A drill to make some pilot holes and 11mm   13mm spanners are required, so make sure you have them. The instructions are very good, items clearly marked including the screws, nuts  bolts (see photo). Only improvement I would add to them are at section 2.5 - to fully tighten items BET  AAO (see photo). I would definitely recommend.
