The charger came and made a pretty solid impression. However, it invited to only one of the two batteries. By contrast, both were right on the camcorder are loaded - so broken charger, probably due to manufacturing tolerances at the charging contacts.
Have the unit then swapped after consultation with the dealer - thanks for the quick and easy handling!
The replacement was then completely OK and doing for a good six months still easily their service.
So, an attempt is worth the charger, but only if enough time is available for the exchange!
