The healtech is the first quick shifter that Ive ever used, but I bought it for the following reasons. The dynojet quickshifter is just out there......for the whole world to see. Now, there are people on this forum, that have a push pull sensor mounted underneath.....instead of on the side. To me its a better set up appearance wise, but the people that have done it, didnt remember exactly which sensor that they bought. Also the healtech is cheaper. The dynojet comes in 2 pieces.......the wiring......and the bike specific sensor. About 600 dollars for everything....if I remember correctly. But....there is a lot to be said for running a complete set up, from one company. The healtech is smaller, and out of the way. I also like the ability to monitor the sensor, and the workings of everything from my phone. It was very easy to install. It interrupts ignition only. It can also be used for downshifts as well, as well as part throttle shifts.
