LOTS of parts.  NO instructions.  I am faced with the daunting task of trying to figure out how to put it all together.  And it is not intuitive.  In fact, it looks to me like some parts might be missing.  Terrible to ship such a product with no instructions.  I do not know where to put the screws, what order all those parts go together, how to raise it once assembled, if ever, how to tilt it, how to turn it, nothing.  Nada.  Not even a picture of the thing assembled.  If I could award negative starts I would.  Because this is going to cause a lot of heartache getting together, untold hours.  And once together, I do not know how much weight to put into it to hold it, how to position those bags under it...  Go the other way and avoid what is likely to be a painful process of repeated trial and error. They say that a one star rating is "missed the mark".  I would say they didn't even try to aim at the mark.
