I bought 5 of these and they had manufacturing errors, they were all pitted in exactly the same way so the hard coating wasn't applied correctly. The guy replaced them with Panasonic discs which he packed too tightly and the cross hatch pattern from the sleeves became imprinted onto the discs rendering 2 of the useless, so be wary of 'repacked' discsI third the eBay suggestion: you can get some great prices on Verbatim repacks there. That's where I've bought all of mine and they were printable too, so that's a nice bonus.
