Was looking for a TV keyboard (with trackpad) that connects via bluetooth. This one connects via Bluetooth and a Logitech Unifying receiver. Uses 2 AAA batteries and lasts 12 months. I already have a K400 but wanted a bluetooth connection so that the receiver isn't taking up a USB port.
It has a special mode to connect to LG OLED TV's:
Select your system to optimize the keyboard. Press the combination from the list for 3 seconds:
fn + 4: Samsung Smart TV
fn + 5: LG Smart TV
fn + 6: Android TVs
fn + 7: Windows
fn + 8: macOS
fn + 9: iOS
fn + 0: Chrome OS
RRP $119 but usually around $68.
