I bought 2 of these systems for our walk in closet. We put one against the left wall, one against the right and had enough pieces left over to make one long shelf on the back wall. The closet looks amazing compared to how it looked before with the awful white wire shelves. The wood gives the closet warmth and color. My husband and I put it all up in about a day and half with many breaks in between. As others have mentioned, the measuring and making sure the configurations are correct took the most time. Make sure you have an electric drill/screwdriver on hand as there are a lot of wood screws that need to be put up and doing it by hand would take a really long time. The only slight problem we had is that some of the wood pieces had little dents in it. The wood is soft and even banging something against it would cause some damage so definitely wouldn't recommend this for a child's closet where they will be putting things away on their own. The dents are barely noticeable and the system does come with a wood colored ink pen to fill in any bare spots.
