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.
This is a wonderful product . I managed giving my hubby an amazing haircut and inspite of it being my first time this product helped me handle this art like a pro :) I did check out many utube videos prior to getting into this lol but end of the day the star remains this product .
