While the design is fine, the construction is the definition of sub par. The hubs used to retain the discs are utterly worthless. My S1 box arrived today, Canada -> Houston. I have looked forward to this day for years. I had noticed others posting about problems with the discs but crossed my fingers. Disc 1 is fine. It is the only one. All the other discs have scratches to 1 degree or another. Discs 4 and 5 were loose, and have sustained heavy scratching. Discs 2, 3 and 6 were not loose, but are scratched as well. I will be returning this set, I have no other option. What makes this so indefensible is that 1 minute's evaluation of the case would have reached the same conclusion. When you insert or remove a disc, you can tell by the amount of resistance that the hubs are completely and totally inadequate. In my 4 years of DVD purchasing, throughout the 600 discs I own, I have not seen a more worthless hub. Continued use of this design will only lead to more and more returns to your company. I can only pray that the 2 sets I ordered as gifts for other people arrived intact. But given the inherent shortcomings in the hubs, I would put the odds at 1 in 50.
