So first I did not really thought before my order, I ordered for my wife who tired to have the TV in the room so I opted for that key to her laptop suddenly the l installs in its asus tablet no disk drive so I downloaded the application and then I plug the key + antenna and boom there !!! All strings are recognized in the first scan chain ... Impressive !!! I still test a few months and then I still takes 2 one to the kitchen and one for the game room!
