I recommend, however, as the first action, a firmware update via the website of Samsung. My unit had the firmware TS00 (also available on the device bottom), I have carried out an update to the firmware TS002. By the way: An update tool is located on the supplied software CD - very comfortable!
As a small drawback I see something short USB cable supplied with the device. I have replaced it with a compatible longer with only 1 USB connector, since 1 USB port usually ranges from totally, only if your USB port should not provide enough power, the 2.USB port for zusätzlchen power supply is needed ,
From me there is 4.5 stars - a half star deduction wg. the short cable.
But since there is no half stars, I round up to 5 stars.

Update on 10/20/2014:
Even now, after more than 2 years in operation, there are no problems with the Samsung burner, I am still very satisfied and would recommend this device without reservation!
