Not usable, what I worried it

I bought this for my external CD drive hybrid PC Asus T100. Music CDs and the installation CD he reads, but no DVDs although 'DVD multi recorder' it says. The Verarbeitungsqualtität is typical Samsung, Plastic as far as one can see, that is just a matter of hours when the device begins to fall apart. I had clearly expected better of it. Too bad, I would have spent the money better for something else.
