Got Roberab Duo for my Ford Ecosport and been using it for about 15 days now. First thing I noticed is that the overall bounce and shake when going on bumpy road has reduced to a noticeable extent. I also found the overall road noise to have reduced to some extent. Really cannot comment on the "car touching the bumps" since the overall road clearance of EcoSport is high and never experienced it earlier as well. Overall, I am happy with this purchase.
