I still have the original ROKU remote for another TV and it has a range of at least 18 feet. This one (Gvirtue) is not very effective above 8ft. And even at that distance, you need to make sure the window receiving/transmitting the signal is at a certain angle to the receiver. That requires all sorts of moves, like signaling the next draw from the side! All of this was done with a new set of batteries.
