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 bought one earlier but it could not download from Asustor app store, could not upgrade firmware. Manual installation is okay. Because the reduced price (I think Asus is finishing this line so sell in lower price). I returned it and bought another (no replacement warranty). Now the new is okay, so far so good at least.
