The Logitech K400 Plus keyboard with built in touchpad is on sale for $18.99 today only. That is lower than its very popular Black Friday sale and is the new lowest price this keyboard has ever been. 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 buttons. This keyboard uses a USB dongle to a achieve a connection that’s slightly more stable than Bluetooth based keyboards, so it works with the 1st and 2nd-gen Fire TV, but not with the Fire TV Stick.
