Bought these about 4 months ago. Have burnt 100 DVDs, not one coaster. Have bought another pack as they are such good value for money. Only 4 stars because the Play packaging was not good, put in a box, no bubble wrap, so by the time Royal Mail had played football with the box, the box had split in places and the shell casing was cracked. This is how the second batch arrived, complained to Play.com, given refund and comments passed on to warehouse manager. Hopefully he'll take note!!
I've soon used up all 100 discs, not a single failure! And they're very nice too, not as blue as on the photo but actually very light, almost silvery blue - compare that to the mega ugly Maxell discs!
Why not 5 stars then? Well, I'd wish for some discrete lining helping you to write straight on them! :P
