If the TV mentions USB HID or your USB PC KEYBOARD works then I like the K400 Plus for price and battery life. I don't sit in the dark so no need for the light for me.
TL;DR Have the k400 plus, would buy again.
I have been reading about wireless keyboards for these TV's and wanted to see what most people are using.
I have been considering either Logitech Illuminated Living Room Keyboard K830 or Logitech Wireless Touch Keyboard K400 Plus.
K830 is backlit and bluetooth compatible but almost 3x more.
Thx (I have a J6300 Series)
