"This is not an air conditioner; it is an overpriced personal fan that makes you damp."
The '3-in-1 Portable AC' claim means it's a fan that blows air over a wet pad. It will not reduce the temperature of your room; it will blow a small, localized stream of damp air at your face.
This is for someone in an extremely dry, desert-like climate who needs a minor, localized cooling sensation directly at their desk and understands its severe limitations. It might also serve as a small, personal humidifier for a tabletop.
Anyone living in a region with moderate to high humidity should avoid this, as it will only increase discomfort. Buyers needing to cool even a small room will find this completely ineffective. A standard fan provides better air circulation for a fraction of the price.
