The battery pack worked fine for about a year and then the charger stopped working. It didn't completely charge it because of that. For that matter when I got it, the charger smelled like burnt plastic. A few months before, it would keep flashing the red light while plugged in. That one probably is just faulty. The camera works well, but it's getting worn out due to me charging with this piece attached all day.
Output:
Bad review
