Im not sales rep you BOFFOON! Im just trying to help some ppl with some discs that work for me, ive seen too many times ppl buying dics only to find out that they make nothing but coasters half the time, thats all. And like i said i use Riteks, Optidiscs, DVD Pros, but the Extreme 4X dvd-rs are the cheapest by far that have worked for me and my friends...
