I have no preference. As long as it vapes when I press the button, I'm good.
But if I did have a preference, I would like it if one of my mods made a clicky sound 6 seconds before sounding a train air horn. Something like the Viking Horns V101C a train horn kit designed to fit any vehicle, or vape mod. It has three, chrome plated trumpet horns that have the ability to reach 149 decibels.
I would love to pull up behind a bunch of cars at a stop light and give that a go. Take a vape, 6-5-4-3, and then hold it outside the window 2-1.
