Well, I guess the main problem with that first review is that the "sturdy hinges" hes referring to don't have anything to do with this product since this product doesn't come with hinges. It is suggested that a standard cabinet hinge be used but this isn't a feasible option either since this product doesn't come with any sort of a limit stop to keep the thing from hitting the floor when you open it. Whats even more dissappoiting is that revashelf doesn't even have any sort of limit stop to go with this item. So I would say they have thought this one about "half" way through before putting in on the market.
