PRIMEON CD-R 80Min/700MB/52x Cakebox (50 Disc), black-vinyl-disc Surface

Recent reviews suggest problems with these. I took a gamble as have used these before. I''ve used about half of them so far and haven't had a single coaster from them. As with any disk, I think it probably depends upon the software and hardware you are using, as too the results you get. I can only speak from my experience and I would certainly buy again.

Unfortunately I can only burn with 4x speed with my asus external burner

Good

Not a single disc has burnt in any optical drive at any speed. These discs appear to be nothing more than black plastic. Total waste of money.

First time tried black layer BD discs. No problem burning. Best price too
