installation is easy with delivered tool. parking sensor works well. shown distance on display is less by 0.2m than reality, but i consider it ad save gap.
It took 40 days to arrive. I did a test,and all sensors are working. Gray color match the color of my car(VW,ld7w).The only thing I want to mention is the manual,the installation instructions.It is the cheapest part in this package,why don't make It better? Thanks
