I have been using Roger car products for quite some time and am happy to endorse their usefulness. My Nano car was fitted with Rogerab in June 2016. Then I purchased Roger back rest and tyre airpressure unit and engine oil additive. I am happy with all the above products. Recently on 24-10-18 my car Indica Vista was fitted with Rogerab Duo.This product has been improved with latest technology by your company.With the latest advancement in technology I would like to get rogerab replaced by rogerab duo in my nano car.
