Satisfactory camera with the following +/-:
Positives: Mine is really wide-angle (I don't know what the other kids received who say the opposite, but mine is). It has a very good image, you can see the entire space behind the car (like the factory ones), it is extremely clear and with excellent focus throughout the range. It is small, about the size of a parking sensor.
Negatives: The LEDs stay on permanently as soon as it is activated (= even during daylight hours) and they are also very bright. This is not very discreet. It is made entirely of plastic. Also, it has some holes on the back that definitely do not make it waterproof (although it is supposed to be the part inside the bumper). Personally, I filled it with silicone to make sure it doesn't get water with the first splash. Overall, it does not seem like a durable component.
Of course, due to its low cost, no one can expect an exceptional camera, time will tell its durability, for now, it works perfectly and I am satisfied with my choice (as long as it lasts, of course)...
