Was so surprised really, had previously always the nonprintables DL Verbatim on the 10Žer spindle and liked my LG GH20LS15 (Renesas!), Not so in more than 4x there was only beer mat. But these here are high already ne corner better. My Pioneer 115 burns the things perfectly 8x, 10x my LG even without errors and read speed is consistently great! My Pioneer shows the readout of the LG-brand as the 17.5 megabytes / s, not a bad value. So strong buy recommendation!
