Excerpt: The thickness of it makes it almost unusable for attaching the go pro to your chest with the chest harness. It comes out an extra quarter inch or so which makes it very hard to position the camera correctly on certain mounts. While I was skiing I was unable to tilt the camera up high enough to show much of anything besides the ground because the back keeps hitting the bottom of the mount.
Excerpt: I bought this just before my trip to Disney World as I knew that I wouldn't have a whole lot of opportunities to charge my internal battery during the day. This seemed to more than double the life of the battery. To give an example of how long this battery lasts, my wife accidentally turned on the camera and started recording with it while it was packed in our backpack.
Excerpt: Works well to keep our GoPro on line for greater amounts of time. Doing analysis of crash tests the cameras can be set and not worry about minor delays and loss of power. Fit just as if te original with little adaptation.
Excerpt: It is a useful product, but most needing extra battery life would like to also frame their shots with the LCD. Iphones are for suckers. The rest of us just need a simple port that lets us put the lcd pack on this. Seems like a major oversight.
