Assembling this metal storage cabinet is a two person job, and took 1 1/4 hours with one skilled person and one who just follows the lead of the first.  An allen wrench is provided, but I would advise using a power drill.  I'm not sure how much headway you would make just using the provided tool.   The unit was packaged well, but the majority of the pieces were not marked and most were bent.  We used a screw driver and hammer to get them in shape for assembly.  The directions were confusing when it came to getting the back pieces on (photos attached)  and had I been doing it myself, I'd have called it quits.  Once together, it makes a sturdy unit and it does come with ties to attach to the wall to avoid tipping.  It has three shelves and will hold quite a bit.  It also has a key lock, which I doubt we'll use, but it may come in handy for others.  Once assembled, this makes a great addition to the garage, but getting it to that point could be a game changer for some.
