The overall quality of item was not up to par. Shelves arrived with dings on the corners, but I thought I could work around them.  Assembly was no problem but the fact that two of the shelves didn't securely attach to the others and were just "loose" didn't make much sense to me. I made a template and marked off the wall where the shelf was to be installed.  I purchased sturdier dry wall anchors to replace the ones that came with the shelf.   The back of the shelves was so thin that when we installed it,  the cardboard like material at the mounting holes tore, making installation very uneven.  When we took the shelf down to assess the situation we didn't have a good grip on the "loose" shelves and they came apart from the unit and dinged the wall as they fell to the floor.  This left the shelves in no condition to put back up.  I have patched and painted the wall and moved on.  I would definitely not recommend this product.
