The touch screen is very responsive and just takes a few taps or swipes UP, DOWN or RIGHT to allow you to select the output modes from wattage/Voltage/BYPASS/TC(Ni,Ti,SS,M1,M2,M3) and CPS (Customizable Power Settings).
It can also be used to access all of the other functions of the mod, such as Modes, Data, System, Time, and About, the last of which allows you to view the firmware version and also gives a QR code, which you can scan to access the Aspire website for more information. By swiping or tapping through the various options it is simple to adjust additional settings such as the vape time, screen time and clock time etc.
