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.
Nice unit overall, as far as materials and appearance, but the switch is poorly made and the light won't turn on quite frequently. I finally determined that it I slap the unit the switch will work. I don't recommend this product!
