This thing is fantastic im using it with kali linux on my raspberry pi 3 and dual boot on my high performance desktop laptop and on all three machines this thing performs within 20 or so of my 40 alfa and it performs within 30 or so of my 60 alfa and to be honest i was expecting it to perform about as well as a turtle on a drag strip and i was buying it just really for the antenna but im really glad i took the time to set the firmware up correctly please dont tell me it doesnt work if you havent taking the time to work on firmware this has to be done correctly
