External burner for iMac

Because in my iMac Late 2011, the internal SuperDrive no longer work properly and I did not have expensive repair, I micht chose the Slim drive. Per USB plug into the hub, no external power or software is required.
Not very loud and very easily.
A driver CD is, but I have not used.
My test DVD were written all clean.
Only after inserting man push the button on the drive to start it needs.
