Meaty part from review: "This is a huge problem. If anybody knows the MAC address of one of your sockets, they can control it from anywhere in the world. You can't set a password to stop them, and a normal home router configuration won't block this. You need to explicitly firewall off the server (it's 115.28.45.50) in order to protect yourself. Again, this is completely unrealistic to expect for a home user, and if you do this then you'll also entirely lose the ability to control the device from outside your home."
