For my new Panasonic DMC-FZ100 I needed a second battery, and the original was too expensive. Due to good reviews on Amazon I decided for Lookit brand battery BMB9E. The battery came very quickly and was packaged very well. The battery fits perfectly into the Panasonic-charger, the charging time is normal, and the FZ100 "swallows" the alternative energy source without problems. As is known, the battery level will not be displayed in the camera (see description), but that's no problem. I am both with the battery, as well as with the purchase very, very satisfied and can only recommend the product!
