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.
Amazon should not allow this product in their site. It goves misinformation using pictures which shows fan rotating..it is just simple plastic only, thin and indurable. Charging it 2999 for this plastic demo piece was the most sinful part.
