    Comments about AKG CU400 Battery Charging Unit:

    We use these chargers in classrooms, some of which have one mic and some of which have two. They are well-designed to accept the mics in the correct orientation for charging, and it's difficult for faculty to NOT get the mics inserted correctly.

    I have two quibbles about this charger: first, the charger's footprint is large and it could have been smaller; second, the plug for the AC adapter sticks straight out the back of the unit, so it can't be positioned up against any flat vertical surface.

    The AKG mic system performs well, and this charger does as well, so I gave it four stars.
