The Logitech K400 Plus keyboard with built-in touchpad is on sale for $17.98 at Amazon for today only. That matches 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 is not a Bluetooth keyboard and instead uses a wireless USB dongle to connect. That means it will work with the Fire TV 1 and 2 out of the box but needs an OTG adapter to work with the Fire TV Cube, like this one, or an OTG cable with power to work with the Fire TV 3 and Fire TV Stick 2, like this one. This sale is part of a larger sale where multiple Logitech accessories are discounted until midnight.
