Sony MZ-E30 MiniDisc player (silver). Quantity 1. Used.
** No other items, batteries, or accessories are included in the sale **

Summary:
Sold for Parts Only / Not Working. Possible to power the device with a gumstick battery but it only reads a few discs and even then playback can be interrupted.

Product Condition (Appearance):
Front Face - A few feint marks.
Sides - A few small marks or scuffs on the edges.
Rear Face - A few feint marks.
There are no noticeable dents or signs of crushing.
All external facing screws present and tightened.

Product Condition (Functionality):
The device will only correctly read approximately one in every ten discs. For most discs it either can't read them or reports them as blank when they are not.
The disc it worked well with was a Prime Media 74 that has a blue and white spot design. This is a rare type of disc. There doesn't seem to be any logical reason why it works well with this disc and not others.
