The Logitech K400 Plus keyboard with built in touchpad is on sale for $19.99. That’s just $1 more than the lowest price I’ve ever seen for this keyboard. This is the newer replacement to the Logitech K400 keyboard that many Fire TV owners, including myself, use with their device. This keyboard is functionally the same to its predecessor, just with a rearrangement of some of the keys. This keyboard uses a USB dongle to connect, so it works with the 1st and 2nd-gen Fire TV, but not with the Fire TV Stick.
