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 鶹. It also analyzes reviews to verify trustworthiness.
Very disappointed with Nintendo ds,first no stylus was shipped, secondly the product screen is very dark, a lesson learnt not to buy third party products again. It's a shame that 1 or 2 vendors send inferior products that will spoil it for all other third party vendors, never again.
