Good for the price but not for use in slow speed applications like RC trucks. Because of the power and size, it gets REALLY hot. gives off a slight odor when first used but disappeared after the electronics blew. There are no problems with it as it cools down, but picture quality and signal will start to degrade unless air is blown to cool it. You don't want to touch the camera when it's on because it's hot enough to burn you if you touch it.
