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.
Although this product has not quite lived up to expectations I would be suggest someone else avoids giving it a try. My major problem has been returning this item even though it was fulfilled by Amazon. I have booked two returns and Amazon themselves have booked two returns however nearly three weeks later this item has still not be collected despite me sitting in for days on end to ensure someone was in and various other deliveries arriving from Amazon. Not sure if this is a problem at Amazon or Hermes end but it is very frustrating and am sick of being passed around and still not getting results.
