I bought RogerAb for my i20 Elite around two weeks back. I waited to se it for sometime to get real and honest feedback. Have driven it over speed breakers and the infamous potholes driven roads of Mumbai. I find marked change in the behaviour of my car after installing the RogerAbs.I have driven around 500 kms after installation. There is less of body roll and the car eats up sped breakers effortlessly no underbody scraping and noise or roll. Braking also seems to have improved though I am not sure it can be attributed to the same. Overall after two weeks usage I must say I am happy with my decision to install the RogerAbs. A word about service too here. I was interacting with Pratik and he is avery helpful guy to say the least. He was able to arrange installation within 3 hours of my placing the order on phone. Five starts to that too.
