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 was initially happy with the purchase and even bought six mats to alternate while others are being cleaned. However, only after 6 months of usage (mats are washed once in two weeks because I have two sets), the foundation started to disintegrate. Every time I wash the mats in a washing machine, everything is covered in remains that come off them.
