I just used along with my new Sony DSC-HX400V on vacation the bundle. The shop works quickly and well. One just needs to insert the batteries in the correct direction only wg. the polarity, otherwise, they are not charged. But the show thankfully a red u. A green LED as well as the completion of charging. A corresponding direction arrow as shown in the Sony batteries, but would be useful. But do not worry: At least my 400V takes not even the battery when it is not inserted in the correct direction.
The capacity of two battery packs in the bundle I find more than adequate, even if, like me, quite a day times 100 shoots several photos and even rotate HD movies.
A fifth star, I would forgive if the loader is equipped with a status display from 0-100% and the batteries are marked with a directional arrow. Then I would take an extra course for more service in purchasing.
