You get what you pay for!
I had bought a cheaper camera similar to one with LED lighting, and with the first rain, it got water inside and became useless.
I have had this specific one for a few days, but I have tested it with car washes and it has no issues whatsoever!! If anything comes up, I will mention it!
The build quality is excellent! It is not even plastic, it is metallic and has a glass cover on the outside.
Now, in terms of image quality, I am thrilled, especially at night!! It has night vision and thanks to the infrared, it shows clearly even in complete darkness!! Of course, the reverse lights help, but I am completely satisfied with the purchase that cost me around 40 euros with shipping
