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.
HDMI works fine, but the IR extender stopped working in the first week. Once I connected at customer site, it was much troublesome to return for replacement, which would leave the customer in doubt about the quality of the product. I bought another IR extender in addition. It costed me more.
