The package never arrived. I filed a dispute, but good old Ali rejected it, saying I received the packages. The fact that I even uploaded the tracking record from my own post office showing they were still processing it (after seeveral months) didn't matter. I didn't get the package and I didn't get my money back.
I have not yet had the opportunity to try the bluetooth cards, but I am convinced that they will work well, so I give my favorable opinion for the purchase made
