Very good, I installed it internally on the rear bumper, accessing it through the license plate light by opening a corresponding hole without letting it protrude. For people over 60, the infrared lights are extremely helpful at night.

Good camera, it works fine at first. However, over time it starts to let water in (it shouldn't be waterproof) and it rusts, so it needs to be replaced afterwards

For the money, it is excellent. It took me a while to figure out the cables because I had power but no image, but I realized that the red cable that comes with the yellow one on the camera needs to be connected to the red cable that goes to the back. Time will show its durability...

Average image....of course, for 4€ you don't expect much!!! So, 4€ but 6 hours of work to install it by myself (a beginner) and it was a nightmare!!! Good luck to anyone attempting it!!!
P.S. If you're going to pay around 50€ to have a professional install it....don't buy it...get something of better quality!!!!

I have installed it for 3 months now and it works perfectly. Very clear image, good resolution, but I would prefer the lens to be wide-angle. At night, it has a perfect image (even if the camera's LEDs were not working, I would still see well because the car has 2 rear lights). The 2din stereo recognized it on the 2nd switch on-off after I had activated the reverse camera from the settings.
Update 26/1/23: After rain, washes, sun, etc., it still works normally and none of the LEDs have broken. It has paid for itself and more.

The camera has terrible image quality, not to mention that at night, when you need it the most, it's basically useless. I wonder how those of you who have written that it's amazing can say that. I say this because I have tried other better cameras, and it's always true that you get what you pay for

I had a great time. Day and night.
I had bought another one which broke and didn't perform as well as this one.

At its price, it is as it should be. The Chinese android car multimedia 2 din that I have recognized it immediately and works without any problem with its reverse interference. The image is acceptable, clear for the space behind the car, without being perfect, of course. If your hands don't reach, it is difficult to install it DIY, and certainly the length of the wiring from the rear license plate to the front console of the car is borderline to inadequate. I needed to use an extra cable with a patent to reach it to the front of mine, which is an SUV with an extended length.

Good for its price but it bothers us a little at night. Not the easiest installation, at least in my own (Audi A4 B5)

Quite good image and resolution, except in conditions without any lighting where you struggle a bit. Quite durable until after 2.5 years, after many uses and intense rainfalls, unfortunately, the lens got fogged.
