Could no difference to the original Olympus battery BLN-1 notice

Have the battery in an Olympus OMD E-M1 in use.
The Pantona battery can be loaded with the Olympus Battery Charger.
Comparing measurements, color, appearance between the Pantonakku and the Olympus battery, it must be noted that the case most likely on the same injection mold, from the same granules produced ist.- Because I could tell from the performance no differences with the original battery, I can say only - everything the same except for the label. Super value for money.
