The Logitech K400 Plus keyboard with built-in touchpad is on sale for $18.99. That’s just $0.95 more than the lowest price this keyboard has ever been. Many Fire TV owners, including myself, swear by this keyboard as the best bang-for-your-buck keyboard for couch use. This keyboard uses a wireless USB dongle to connect, so it works with the 1st and 2nd-gen Fire TV. It will also work with the Fire TV Stick 2 if you use an OTG adapter.
