To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
May as well blow a fan over a bucket of ice. Which is exactly what you are flogging, unscrupuously. It would not even cool down a paper bag. I bought a 5 blade fan which does a lot better. Yes, I am disappointed in the product and ashamed to have been deluded by the false advertising and not happy with AMAZON for allowing this to be marketed this way.
The cold water doesn't drip from the tanks onto the tray. Water just stays in the tank for long durations which means the blower is just blowing normal air. Not effective product. I think it might be the manufacturing defect.
