Excerpt: A few years back i bought a cheaper battery and always had problems with the quality of the connection to my camera. Sometimes I would lose all power while shooting. I would have to re-seat the battery to make it work again. It has never been a problem with the sony product.
Excerpt: I love this battery so much I have purchased 3 of them. With the appropriate adapter, I use this with my Panasonic Lumix GH3. I literally use my camera for several hours a day, serval days in the week and the battery lasts.
Excerpt: I work with production sound and bought this battery to fit my Sound Devices 633 recorder. It gives me a nice option of powering when my NP1 runs out and i have plenty of time to keep recording and change to another NP1.
