Still works, missing knob, but does not affect performance.
The software on the CD that acts as database and direct control of carrousel works only on Windows 7 or older.
It will not work on Windows 8 or above, but there is third party(itechcds.com) that will still control it possibly in Windows 8.
No box, used as is, will ship for 10 bucks more.
