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 would give this item one star if not for the fact that the seller sent a replacement the next day to try to resolve the issues with the product. But the light did not turn on for the first order nor on the replacement item. I no longer want to keep doing the back and forth and the time and effort it will take to return the items is not worth it to have them keep sending me replacements until I get one that works. I would spend your $20 on a product that works unless you are fine with the light never being on.
