very good product overall.
directions lacking clarity and some seem a bit out of order.
however, product does go together snugly and you can feel the part catch when putting them in, ensuring a snug fit and tight and stable product.

Only downside noted is that the back has holes for shelf pins, and those holes that are not used remain holes... ie, places where water and bugs might enter.  It would be nice if they included plugs, but in any event, we can easily patch over with tape if needed since our unit is outside in our carport area, and we get lots of rain... i will update if something changes.
