I'm not talking about headphones with multiple functions, I'm talking about one button with two purposes, power and temp change. Do you prefer the current setup of a button under the mouthpiece and the mouthpiece being the switch? Personally, I think the current setup is a shitty design. If you would have a hard time remembering to push the button three times to turn it on then I don't know what to tell you. I dont think it's very tough to remember and it is how most oil pens work. Your time must be extremely valuable if holding a button for three seconds is a major annoyance. Do you happen to have any ideas on how to improve the design?
Let's drop the sarcasm, shall we? We don't want a flame war in here.
