Cheap but very good

I have installed this Einparkhile with my VW T4 and am completely satisfied. You will always work perfectly, and also works very precisely. The cable from the control box to the display were too short, despite the 5m long cable for my mobile surfing with long wheelbase and so I had the three signal cables extend (solder). By the way I have the display built right into a blank panel in the dashboard.

The supplied drill hole milled an exact hole in the bumper, so that the installation of the sensors is not a problem. Furthermore, the thinner center drill can be dismantled (grub screw), so you also may remove material without having to drill deep into the material. This feature I could do me good in the Styrofoam behind the bumper to benefit.

Oh, and to all who think the sensors have to be mounted at a minimum height of 40 cm, because it is in the manual:
with me, I could only be installed in a height of about 35 centimeters and I was warned always reliable so far. Even a trailer coupling is not a problem if you follow the instructions to the distances in the manual.

Conclusion:
This product performs reliably its work, while also providing a fantastic price-performance ratio. (Outputs and possibly even hundreds of euros more) Anyone who does not buys is your own fault. The assembly can be carried out also for a layman with little technical knowledge.
So that my descriptions are easier to understand, I present here a few images available:
