The disks are semi-SHITE! I had a load of them and the LG refuses to burn them at 8x. Every one a coater. However, burn them at 4x and they are auperb quality! Go figure...
My BenQs automatically burn them at 4x, and the quality is, again, excellent. Curiously, the BenQs will REFUSE to overspeed them.
So, great burns at slower speeds, but coasters at 8x.
Mine were plain, white top, printables, too. Just coming to the end of my batch of 200! Thankfully.
PS some were terrible after the 3.5GB mark - thousands of error resulting in a 0 quality score.
