Puff count estimates: Manufacturers list “puffs per charge” but that depends on how long you inhale. Ignore the number; focus on battery mAh and your actual usage.

Mesh material marketing: Some say “ceramic mesh” or “quartz” but in practice, the difference is subtle for most users. Don’t pay extra unless you’re a flavor chaser.

LED lights and displays: They look cool but don’t affect performance. A simple battery light is enough.

Weight: Unless you’re hiking, a few grams difference won't matter.
