This charger and battery set is pretty nice, with fast charging rates, a clear and easy to read charging/battery status display, and two batteries that *do not* cause my camera to give me the "The operation and safety of this battery cannot be guaranteed" warning (unlike some of my other 3rd party batteries). The percentage display also functions correctly (some 3rd party batteries just show bars instead of the battery % remaining).

The charger design is sleek and makes slotting in and removing the batteries easy. I don't know that the separating design of the slots from the power base is very necessary, just adding complexity and cost. If I don't want the charging unit, then I'll take the batteries by themselves instead of using the relatively bulkier charger slot segment to transport them. I guess there might be limited use cases for the separating base, but I'd rather see a simpler design that has less moving parts to potentially break and adds costs.

I don't think that's a big enough deal to warrant the removal of any stars from my rating, as the rest of the package works so well. I'm very pleased with these and would certainly recommend considering this kit if you're in need of more NP-FZ100 batteries that are fully compatible with your camera.
