"A pricey, versatile portable fan whose misting feature is more marketing than thermodynamics."
The 29-hour battery life applies only to the lowest, least useful speed. Expect under four hours on max speed, and likely closer to two when using the power-hungry misting function.
This is for someone who values the all-in-one convenience of a cordless, misting fan for casual use on a desk or patio. You are paying a premium for the Shark brand and the combination of features, not for raw cooling power.
Anyone needing to cool a space larger than a personal bubble can find a more powerful corded fan for less. If you live in a humid climate, the misting function will be ineffective. Those needing long battery life at high speed should look elsewhere.
