I was skeptical, I make no secret of it. But now I can say, quite unjustly. The battery fits easily on my HDR CX130, which indicates to me a time of just over 3 hours. The charger is much faster than loading the camcorder. At half the price of an NP-FV 50 you get 50% more operating time and on top of that a good charger. Highly recommended!
