Cons: Low to plastic, blue LED lighting too bright / in flachenem angle badly or can not be read (only if no plan), invites at my house neither expensive brand batteries - Panasonic (2100mAh) Ansmann (2850mAh), Duracell (2500mAh) , Energizer (2000mAh), Grundig (750mAh); yet he invites cheap battery with 1800 mAh! ! ! !
Did I actually ordered this device to my ancient combi charger (which still works) to replace since I usually only need AA batteries. Only requirement for the device was to ensure reliable charging cycle
Actually yes to battery's protect the environment and the currently affordable prices in the battery segment, these are probably more than just an alternative to ordinary batteries, but who has this device brings home truly not much joy and engages sooner than later in desperation but to commercial batteries.
A star was still too much!
CONCLUSION: Stay away and prefer to buy another device! I for one will avoid all VARTA (also because my new car battery after one year only half as much power has). The previous battery, however, has done very well their Service 7 years!
