We picked up one of these for organizing the CDs at work but found it to be more hassle than it was worth. The idea in theory is good but was poorly executed since it constantly jammed or lost the disks making this the worst $100 spent bar none.The problem is caused by the carousel inside being offset by 1 or 2 slots. This causes the device to believe there is no disc were one exists or to eject the wrong disc altogether. I wasted at least 5 hours messing with this pile of crap, upgrading, opening, verifying locations and dealing with the WORTHLESS support site. I ended up tearing it apart to get my discs back.Disc stakka will be stacked right into the trash bin.
