Long long time I searched for a shelf, which has an attractive design, is expandable and pricewise a good compromise. 225 CDs (excl. The upper tray available) at this price accounts for less than 0.25 per CD. Other, perhaps more about nobler shelves cost tw. tenfold. The structure was simple. The sketch is a far cry from the sketches of the Swedish furniture store. A Phillips screwdriver is sufficient completely. The holes in the fittings are well sunk, so that the screws do not protrude and can in expansion modules fit parent / or side by side. For me, unfortunately missing on delivery, two shelves, which were promptly replenished by tel. Complaints in less than 24 hours. !!! The other shelves (DVD, Blu-ray) have identical outer dimensions, so that a combine would realsierbar here. Acrylic happens to have some instantly recognizable dust susceptibility, but that we know in advance, before you buy something. I would buy again at any time (and will acquire additional modules), because it fits nicely in my modern decor.
