Sorry for the late reply. Advantages over competitors are: Plug-n-play over existing CDI, no loose wires, no battery needed and very low power (it will not impact ignition performance), compact and unique design, Spark Magnifier inside and 16 curves that actually make sense. Targets are: Stock engines, Touring setup and Street-racers: Should fit 95% of Vespa and Lambretta with CDI ignition. Because the Smart Booster can only retard, it means that if it fails (unlikely but still possible ) you remove it and you can still run the engine. Of course, you are stuck with static timing. Keep in mind that if you had set your ignition to 28 and it was working fine, then you can still ride up to 4000rpm with very limited risk of overheating or seizure.
