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 can listen to my music from the basement, whilst my PC sits two stories above me. I can also hear my music if I stand outside my window. Good range, though I'm now afraid of being a victim of a bluetooth hack. oh well, at least it works well.
Great kit. I put this into a HP EliteDesk G2 MiniPC along with a new internal Wifi Card. Works like a dream & as should. Can't speak on range since my home is over saturated a bit but I get full strength no matter where I am in the house.
