My honest experience?
My honest experience?? - the 1st Smart Booster died on Sydney Harbour Bridge freeway, in peak hour traffic, after 2 hours use. Very inconvenient & dangerous. Antoine @ Kytronic was sympathetic and replaced the unit, even though I did'nt claim warranty until almost 12months later. So full marks there Antoine!! The 2nd Smart Booster has now run approx 10hrs. Motor is smoother & revs higher. Still need to fine tune timing start point & best curve to use, but it is performing as advertised. Kytronik are good guys & I recommend.
