I have purchased two of the LPBIN2s and I am very pleased with the construction and product. Along with the bins, I purchased the bottom shelf adapter and groove mats for both. The addition of the accessories truly improve the overall displaying of LPs and the groove mats help stabilize the collection. The ordering process via the site was very easy, as well as tracking. The bins arrived on time via UPS. Assembly was fairly straight forward and took approximately an hour on both occasions with just one person. I have a large LP collection and this is a great way to easily organize and catalog a collection. Overall, a great product! As far as the advertised capacity, the 560 advertised will truly depend on your collection and does seem a little ambitious when trying to flip through vinyl. After loading the first bin completely, flipping was restricted and I had quite a few that would not fit hence the second purchase. Again, capacity will depend on your collection, doubles, box sets, etc. Just as a side note, I have also purchased the Wall Bin and am very pleased with that purchase as well.
