Have the unit for several weeks. The awakened by the comparatively high price expectations have not been disappointed. Highly recommended for users (like me) who do not want to invest a lot of time and energy in the batteries are charging, but simply looking for a highly reliable, foolproof to use device that delivers churning optimally charged batteries. No overcharging, no memory effect, short charge times, many batteries at once. Then Substituting even "intelligent" battery, eg Sanyo Ni-MH 2500 (have since 2 weeks despite numerous flash photos not leerzukriegen), the Digital untroubled fun, nothing stands in the way.
