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.
My wife purchased this as she wanted to wave her hair for a particular event. It was very affordable and left her with a very nice more natural wave. It is so much nicer looking than crimping for a similar effect. It worked well, she was very happy with it, as was I.
