Bought two of these to hold about 1500 CDs. I had to attach them to the wall with additional brackets besides the cloth strips that come with the rack. The reviews did mention that the shelves were unstable, so I can't say I was surprised, I knew what I was buying wasn't very good, but the quality of construction, in addition to the lack of stability, earns this product a one star rating from me. In several instances, the metal bar welded on each shelf along the back to prevent CDs from sliding through was too long and was bent accordingly. The shelves themselves need another metal bar to keep CDs from slipping down to the lower shelf or not slide in the shelf all the way. In all, I would say this is poor quality, even for Chinese made junk.
