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.
Not the quality I expect from Simplehuman, cheap plastic with plastic chrome coating. Works but takes quite a few pumps to get enough soap, Don't expect it to last a long time but it looks better than the plastic liquid soap dispenser that you buy in the store.
