Some numbers sound impressive but don't matter much in practice:

• Puff count: There's no standard for how a puff is measured. It's not a reliable indicator of lifespan. Use mL instead.
• Battery mAh: It's good to know, but it doesn't tell you how long it'll actually last. Usage patterns vary.
• 'High' or 'extra strong' labels: These are subjective. If the label doesn't have a number, it's not worth your time.

Don't let flashy specs distract you from the essentials: strength, type, and volume.
