Super - fast delivery
Super - can all inserted CDs / DVDs read Win7, WIN_XP & Xubuntu - many data & programs are just still provided on CD or DVD.
Super - can boot from WIN XP & Xubuntu CDs - is then but sometimes very helpful when otherwise it could not be more ;-)
Super - can burn CDs and DVDs (CDBurnerXP or K3B) - on my laptop, although only with the 2nd USB cable for power supply - but PRIMA
Reading went with only a USB cable without problems.
Simple simple case here with the small pocket, a great thing for traveling.
CDs & DVDs are just still cheaper than a USB memory stick to pass on to larger amounts of data.
Blu-ray I need not - that's why for me an excellent price / performance ratio
