I analyzed buying this product to the Nth degree and finally ordered it last week.  So glad I did.  It was delivered faster than I expected.  Every piece is numbered and very easy to put together.  The holes lined up nicely.  You don't need any additional tools.  The allen wrench is included.  Looks very beautiful in my living room beneath my 60" wall mounted television.  I may end up buying a smaller one for the tv in my bedroom.  Love it!
