Hello, I don't know what GEN2 AFTT means. I saw an offer on Amazon yesterday for 23 euros (Black Week).
There are extra buttons for Netflix and Amazon Prime and others on the remote and in 4K.
I assume that this is a further development of the stick I bought. The stick works flawlessly and is worth the money. Especially useful for older TVs that have an HDMI input but are not wi-fi enabled and don't have a smart function.
