Highlights
Quality
Perfect drive support and plug in capability is fantastic.
A quality item that has increased my bt connection reliability as well as range!
My old asus bluetooth adapter was just out of range, and the music wavered and paused.
I used it to play some rocket league and i had 0 issues, no lag or disconnecting.
Price
Great price, works perfect for blue tooth earbuds, which is what i got it for.
So grateful i can save almost $10 a month.
Price was right too, less than twenty dollars for reliable and quick bluetooth.
Competitiveness
I've now switched to linux (debian, specifically) and had the same experience.
However, it turns out asus manufactured it in china, but i didn’t have any other options.
I chose this bluetooth adapter because it’s not from a chinese brand.
