With the title almost everything is said! The device is very slim and fits in your laptop bag with the laptop inside. The material is very good, in a black metal finish. An absolute plus point, because I really have to give 6 points: the external drive can be powered using a USB cable! Both power and data is exchanged over it. That means you need no extra power cord or plug - great, great, great.
The burner works, of course you can not expect high-end device, it does the job and really good. The drive itself can play DVDs as normal without delay or stuttering. However, the drive is like to somewhat louder because of the low altitude when it has to read much of a DVD - but that's not bad and quite clear in the flat construction.
