I use these cases to organize and store my Blu-ray collection. These are by far the best storage system I have found. I own a couple discgear cases but they are limited in how many I can use since they cannot be stacked on top of one another. I now have 7 of the CDBP-100-OP, 4 of the CDBP-200-OP, 2 of the CDBP-200 and one of the CDBP-400-OP and use every one of them. They are very well made and sturdy, are extremely space efficient and look great. I love everything about the cases except for having very few retailors to choose from leading to high prices. I have only found about 5 online retailors that even carry them. That said I wouldn't buy any other product.
