Literally garbage.  Part “F” had a pressed in nut blocking a bolt hole.  Instead of the factory rejecting that part, they pressed another nut in the end of it, encapsulating it into the part.  

Started to disassemble it to do the return and the entire thing started falling apart.

I can’t believe that there were such good reviews for this.  The quality of materials and craftsmanship is abysmal, and clearly, lacking Quality Control at the factory that makes this thing.
