This is a handheld pong. The biggest paddle includes the system hardware. The second paddle wich is smaller (1/3 of the system size) is attached to the first one but could be detached. Thus, this is a real portable and easy to carry pong system.
The 677 is different from the Hanimex 666 in that it can play 2 shooting games with a light gun.
