Very satisfied with the way seller do by setting the tracking number to my email and gets the updated by email ... super smart. Product concerns I 've not install yet too busy now.
Hi to everyone! Installed these on my W211 2007 (facelift) rear and they work great. I painted them lightly to the matching color with the car, and they still work. I can't compare them to the original ones, because all 4 sensors on the rear we're already broken when I got the car. I have reversed couple of times now, and everytime they have worked as expected. Thank you seller, I recommend! A+++
