Got these yesterday, not very pleased (and they were advertised as Prodisc s04). Bulkpaq 8x Generation 4 dvd-r. Some discs visibly damaged and dont seem to be up to the same standard as the Datawrite Fuji03. Im currently beta testing a speedhack firmware and these give up before 9-12x whilst Datawrites seem to give up at 13x. Though these seem to be OK at 8x (theyre rated speed I dont think they will last to long (i even got coasters using these with stock firmware at 8x). I'll never buy bulkpaq again!
