i love that 2 dvds/cds can fit in one slim case. out of the 50 i've used so far, there's been no breaks. although the plastic isn't solid, which makes it seems cheaper (and may be why it's so inexpensive), the flimsier plastic makes it indestructible from dropping it.
the only gripe i have is that the sleeve insert goes through and through. it's not sealed on the bottom, so whatever sleeve you put in has a decent chance of falling out if not sized right. it's not a deal breaker for me though. i'm going to keep buying these. great value for a great product.
