This arrived and was not constructed as it is shown in the photos. All of the bars are straight. It didn't have the diagonal zig-zag bars that add strength and support. 890 CDs is not very light. It is easy to put together, but the plastic clips didn't always hold well so it took some time to try to get the whole thing to sit properly. It could use a center bar so the CDs don't fall into the shelf below when loading them. The dividers are good and necessary and will hold the CDs up if the shelf is not full. If you are not into putting holes into your wall, don't buy this. It definitely needs to be strapped to the wall. The two included straps work well, but the tiny anchors might not be enough to hold it if there is accidental pulling on the unit. If your wall is drywall, I would recommend buying separately and using 8/32" or 1/8" toggle bolts.
