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.
Have been using this system for a few years now, it works so well to keep the nasty nappy smells hidden! always try to grab a box or two when I find on special elsewhere but am quite happy that I've found them at such an amazing price on Amazon delivered strait to my door!
The product was good but the way it was packed for delivery to my door was rubbish. The sticker that held the flap closed was not holding and entire contents of the parcel was about to fall out. Not good Amazon very below even average.
