I saw a YouTube vid with a similar, if not same product, and the guy in the video had similar difficulties with the vape he was using. I distinctly remember he pressed the button five times and nothing worked. Then he tried pressing the button slower, then faster, and finally got the thing to work. Similarly, other button presses for heat level, etc., were a problem for him, but after playing with the thing for a time, he finally got it to work. Hopefully this is the case with mine.
