PDC for the small purse.

I was looking for a simple parking aid with no frills, which is quick and easy to build in and doing its job reliably.
After less than 5 minutes search I came across this product and apparently seemed this product to meet all requirements:

+ Low
+ Simple installation
+ Any additional "features" -> purely acoustic warning
(Saves time and hassle during installation, since everything can be installed at the rear and no cable must be routed into the interior and, for example, to build in a display properly)

The PDC does exactly what it should. Strong buy recommendation.
One star deduction there, because they somewhat slower to react obstacles as a factory installed PDC. But who does not want to overly fast to park backwards, which is to recommend this product highly.
