The performance of the battery, I can not judge, but the battery is minimally smaller than the original battery, which means that on the one hand the charger the battery does not recognize right away (insert only after repeated and some wiggle) and that the battery is not so simple can be engaged in the camera compartment: he stumbles on the one hand, does not engage the hooks of the bracket, he stumbles on the other hand, is the hook in a position in which the cover can not be closed. After several attempts the battery fit then, but I would have expected that the battery apart from the performance at least promises the same handling as the original.
Two stars because I have then nevertheless still somehow get it to work. But with me it is definitely only for absolute emergencies it - not recommended for continuous use due to inaccurate fit!
