Query: Not suitable -

8X disks are difficult to find. Locating them on Verbatim was a bonus, I thought. Verbatim was a name I relied on. The disks are not suitable for dubbing. They will not allow playback or finalizing. I was so excited at finding them and ended up having to discard DVD recorder on which I planned to use them. I will never purchase Verbatim again. It was the fault of the product, not of Amazon.
