Query: My room is finally safe! So cool.

This item is so cool! The technology is incredible and it really works. You place your eye against the viewer and blink your code when the different colored lights appear. The Room Guard even has a voice that talks to you. I usually use "green, yellow, red". When you blink your secret code the flap springs open to reveal your door knob, or door handle. My favorite part is when I put my code in, I get to find out how many "intruders" tried to get in. If someone blinked a wrong code (examlpe: red,red,red) or tried to move the room guard off the door, I'll be told by the voice that I had intruders. I even know a BOY that bought one for HIS room, what a great item. The store near me is already sold out.
