I bought a couple of these batteries because I read the one that comes with the Kodak PlaySport 1080p Waterproof Pocket HD Camcorder (Black)
does not last very long. I needed extended capacity and due to the very low price I picked two of these up.
-Bigger capacity then the official Kodak battery
--It's a battery, there's only so much I can say.
-None, how it looks maybe? But even then, who cares, it's in the camera...
Summed up: If you're getting the Playsport HD, get at least one of these too. Believe me, it's worth it.
