Received the package. It comes in a carton box. Put on the antenna's. Powered on both deviced on USB power supply. One is preprogrammed to send packages. The other is preprogrammed to receive packages. When I unplugged the power on the sender, it kept sending. Ditto for receiver: on unplug it kept on receiving. I cannot yet say much about how long the batteries will last. So far it looks OK.
