The BDR-209 is indeed one of the best drives available.
–> good quality BluRay burning for all disc manufacturers
–> excellent quality CD& DVD burning, even for old and unknown MIDs, 1x, 2x and 4x speed discs, where most of modern drives produce garbage. mostly the best jitter you can get for DVDs & CDs
–> it reads bad BluRays, DVDs, CDs where most of other drives fail
