The positive reviews are all related to the battery. The can wholeheartedly endorse. However, at this point I would like to evaluate the Sanyo charger, and that is a disaster: not only it turns off only after 16 hours, no matter how the respective charge status of the batteries is - it is almost impossible that the inserted cells without a pointed object or a knife to pry out of the device. So you should buy the batteries separately.
