It's 1:15 PM, and you're between meetings. You've got ten minutes to decompress. Draw-activated hardware is perfect for this moment: one hand, no looking, no accidental button presses in your bag. It's also more discreet if you're stepping outside—just bring it to your lips, inhale, and it looks like you're sipping a drink.

Button-activated devices, on the other hand, give you more control over the hit. If you want a longer, slower draw at a lower temperature, you can hold the button and adjust. Some people find that consistency reassuring, especially if they're using the same cartridge all day. The trade-off is that you have to be deliberate about the button press—easy to skip if you're distracted.
