Summary: I have had this for a few years, it old now, so I am only posting for info of current owners, no reason to buy one now. I needed to replace the battery, which is 'sealed', and Sony wants $93 for a replacement, plus labor, since they want to install it. To remove it, you have to remove the 2 tiny screws on the same plate as the memory card, and carefully slide/pry the panel out. After that, it slides right out just like any other camera battery.
Summary: Video quality is really bad in low lighting but the picture quality of the camera function is surprisingly good. The camera feels cheap since it is all plastic and the ergonomics are really bad. Button placement is really odd. Overall not so good but for the price....you cant really find anything better.
