TX-Cam is at 50mW RF power, picture is clear with good colors. The IR-LEDs enable you for night vision (you get a black/white result then) at decent video quality. (and you get 2 of them ;-))
The RX ... well, it works but I went for a different model where I can switch channels instead of using a potentiometer (Cameras transmit om channel 3). On the other side - again, for this price it is a bargain.
Pros: TX Cam with 50mW RF power, can be used in voltage range from 8-12V. IR-LEDs work great in darkness, Lense is interchangeable., 3 power supplies 2x9V for the cams and 1x12V for the RX are included, great detail: as I am based in EU they came with EU-plug.
Cons: not really any, the cams are a bit heavy compared to the size (metal case), the RX could be more sensitive (or at least upgrade for a better antenna).
Over all: 5 Stars, I am verry satisfied and happy with this product.
