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 analyzes reviews to verify trustworthiness.
I started my journey in using a Japanese brand detox patch, and they worked so well for me. my quality of sleep improved significantly. BUT with this brand, the stick quality is so low and they kept falling off my foot the entire night. At the end of day, my sleeping quality got so bad because these things keep distracting me by moving around.
