This caught my eye as the box specifically has a feature icon for 'low standby consumption' - haven't seen that before. Kenwood lists all their units as under 1ma, so I wonder how low this one specifically is.
It also weighs 600g, so about half of what a normal cd player would weigh, and potentially over 1kg lighter than some OEM units.

All for around $50.
