Working distance is about 3 meters. If you go further away the remote stops reacting, you need to hold button and wave the remote till it starts catching the signal opened the receiver, small circuit inside, havent found anything similar to antenna... I need to figure out where to soldar a wire to get a better signal. If I'll get it, I will put some photos with additional feedback. This item got 2 stars only because of fast shipping.
