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 just love this product. The quality is good, fits well and also keeps me warm in so much low temperature(it's around 3-5°C over here now). I'm even ordered another one for one of my family members. It's highly recommend just go for it
