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.
I wish I knew how this happened, but I was looking at the 7kg bag for $19, and had to step away from my computer. When I got back to my desktop, THIS page with the 7 POUND listing loaded, and I clicked add to cart, and was sent this tiny bag for $19 ... Rip Off!! I think there's some kind of bait and switch in the program when a page goes idle. I got hoodwinked by seller, but ultimately it was my fault because I didn't confirm at time of checkout. Be Careful! Oh, and the bag had a rip in it, so I lost even more substrate along the way. Could have returned it, but life events prevented me from doing so.
