I've had my iball for several years and really like it. Two things, for whatever reason, the camera seems to prefer Duracell batteries and works best on them. I've even talked to iball and that is what they recommend. The other one is to make sure to keep the magnet on the camera clean so that it doesn't scratch your vehicle.
