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.
Awful! I was so happy about it but when I installed one don’t turn on, I’m so disappointed, I got the highest expectation but they don’t work. Don’t buy this! The quality of this product is so cheap! Do you a favor and don’t pick this set.
