Don't forget there is a fundamental difference between the way some people view temperature control and the way Evolv view it. A lot of users see TC as a way of controlling the intensity or heat of the vape and want to be continually adjusting the temp, whereas Evolve see it as true temperature protection, a way to stop you burning your cotton and avoiding dry hits. If you look at it from the manufacturers perspective there is no need to be continually adjusting temperature, it's pretty much set and forget.
