After a long odyssey with Logitech I ended up in this quite inconspicuous FB - and am satisfied. no high-tech display or pesky installation software more. All devices are programmed with code. Teach extra keys, volume control and, Macros all appliances - all done quickly. With the optional wireless sockets simply a hammer device for the price. It has a 4 times as expensive Harmony replaced, and may more. Radiation exemplary. Is great in your hand - no eternal up and down slides on key search. Only the keys could be illuminated, but well beyond the price range. Oh, batteries never seem to go all :)
