Man... I wouldn't use this on my front door, kinda risky. But it's a really great idea for something fun for a kid's bedroom or something! :D

Why do so many assume that it must be used on the front door (or any entry door) to your house? It would be amazing for children, or just plain a neat piece anywhere else throughout the home.

yes i know wat a deadbolt lock is and i also know their placed right about where the bottom suction cup is. placing it lower is impractical such as this entire invention due to the noise. nebody could hear u program the knock b4 u leave and bam! ur a broke joke
