To calculate the overall star rating and percentage breakdown by star, we do not 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.
Have always use this on our kids, but amazon has the best price for these huge bottles. Kept the small 200ml for travel and baths at other families houses. These large ones have great pump dispenser. 1 of the 2 arrived with the spout broken off so amazon refunded.
