The device is great, quiet, super fast, just perfect. More can not be said so. The only drawback. The CD-ROM drive can not read ovens, "eject" only on the file manager. This is obviously a "NO-GO". After a telephone conversation with the customer service of CSL I got an email on how to remedy the defect. The Druckknop on the housing serves as an extension of the push button to the actual Drucknopf of the drive. After a decline in the housing front I could see the extension to the correct position (had still paper if necessary) so that it works now. The pushbutton on the housing is something Schierig print. But now it funtionert. The support from CSL's top. But often I do not need the drive yes. Otherwise the device is great, I would recommend in any case further.
