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.
Do not bought this product. I bought it's 2 times but every time I got mismatched product. When I ordered its first time size is too small then I returned it but I didn't get refund till now. Then I ordered 2 nd time. But this time I bought 7 UK size but in package there are different size 7 and 9. I don't recommend this product. It's totally waste of money
