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.
It's pretty good and I really like it. The only problem is, instructions. It took me a little bit to get the hang of it, but even now, I still don't get how to use this too well. Sometimes I have to button mash certain buttons to click into the things. I can see how people might just throw it away easily, but play around with it a little and maybe you'll get it.
