Wayfair needs to re-evaluate on continuing this product.  None of the pieces were marked. I initially thought, hey there's not that many pieces, it can't be that hard.  Way wrong!  The shelves although they look exactly alike have to inserted so that the back piece fits in correctly.  It became a guessing game with them.  The pieces that make up where the wine bottles fit also have to go in a specific way which again, without the pieces being mark, it was a guessing game.  You will also need small hands to be able to fit them in the spaces to tighten everything.
