Overall, this is a cost-effective solution that is relatively straightforward to assemble. It feels flimsy because the plastic material doesn't feel that solid or durable, and the way it is supported does not offer the tower much structural integrity and causes it to "sway". Fortunately, you can leave it out of the way, and it should last you a long time.
My biggest gripe is that all the Blu-Ray / DVD cases must be balanced between two rods on each lane. It is VERY easy for cases to just "fall through". Often when I am going to get a Blu-Ray, I end up causing a cascading chain reaction where a ton of cases just fall through, and it takes me a solid 5-10 minutes just to reorganize everything again. A real hassle, but given the price point, I can cope.
Visually, it looks good, or at least acceptable depending on your standard. The dark color matches our furniture, and I think it looks nice tucked away in a corner.
Despite it being annoying, it definitely gets the job done.
