Yi Jhan DVD-R

I bought this one to find out how bad it was. It was quite bad :slight_smile:

Still it is fully readable in my 165H and 411S so it isn’t totally garbage… But I care to wonder how long this one will last…

As title,

Could you tell me where and in what price you got those yi jhan001 DVD-R? I am surveying the DVD-R product now and wondering if there is anyone has the same experience of yi jhan 001 DVD-R?

Thanks a lot!

OOPS

I bought them in a local shop, I only bought one cause I knew it was crappy. It was marketed as “AZO”, though the disc itself is completely white, NO serial number or any other forms of identification. Just white. They were very cheap.

Nowadays these “AZO”-discs are Vanguard, not Yi Jhan.
