Bought two sets for the office and children's playroom. Connecting a laptop to a 4K TV hanging on the wall. The stable range is actually only 3 meters (10 feet), not 60 feet as advertised. In both rooms I have no objects between transmitter and receiver (totally open space). As soon as you move it more than 4 meters, it will be disconnected and the TV will not be able to see it. Or the picture on the TV freezes without moving. The only other reason for such a short range is electromagnetic interference. Well, at least this product is either low power (long range) or prone to failure. Otherwise, it works well from a computer to a 4k TV within 3 meters. Can the manufacturer comment on this to help all buyers?
