I bought this for a telephone stand for my wife who is in a nursing home.  Works great! The trick to putting this together, is to have the arms slightly loose, then place the bottom shelf in and align it.  Must have a electric screwdriver to screw in both shelves.  Tighten up the arms with the allen wrench after you screw in the bottom shelf.  I gave it 4 stars for one of the brackets was broke to screw in the top shelf. This did not affect the usefulness of the stand.
