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.
More expensive than some, but well worth the extra.. sturdy smart, firm buttons, robust materials. Does the job and adapts to USB devices needs I have had other cheaper ones that work ok, but not long lasting, and switches failed early. looks nice too.
