As an accessory for MB Air bought separately. Fast delivery, flawless, high-quality packaging. Drive: super compact, just 1.5 Jewel Cases thick, great quality, good workmanship, through the round rubber ring at the bottom of the thing slips on smooth surfaces not away. Only the USB cable is a bit too short for my taste, 20cm more would be nice. Works flawlessly with all installed burning programs (Roxio Toast, Simply burn). Value for money: well, slightly more expensive than other Slimline burner, but the quality workmanship and the Slotin drive do much good again, no wobbly drawer, otherwise when pressing the CD etc flexes the spine. Just be aware something that they are good horizontally drawn into the slot when inserting the blanks / DVDs, otherwise they could be scratched when moving to the edges.
1 point deduction: cable is too short, price quite crisp.
