Pros below: value for money. Pts comfortable, in the process almost does not heat up. not very accurate, but measures the impedance of the battery. qualitatively assembled, spring contact plates. independent charging, even one unfortunate battery, but better in pairs. in three hours I charged 4x1800 mAh almost to the maximum, I switched off myself. just dumb. Its cons: dimensions steel contact fields what's inside is still a mystery The enclosed instructions can only be read under a microscope.
I added some photos to complement my review and provide more context.
