The battery does not charge, so you can't work with it unless plugged into car with car running. Video is okay, but jerky and often pixelates. No decent instructions on how to work it, have had mine for quite some time, it sits on the windscreen looking pretty as I've never been able to work out how to work it, save videos, or download. The app has never worked on the wifi, and in fact the app won't even open anymore. Disappointing, as I expected a lot more for the money. It took a lot of time to find an sd card that would even work, as it accepts very few types. I need to format it, but can't because I can't work out how, and the unit does not stay powered on so I can do anything. Sadly, I wasted a lot of money on something that is just an ornament.
