Review on Enhanced Home Security and Personal Protection with the DJ1 DoorJammer Portable Door Lock Brace (Original Edition) by Tracy Knight

Great idea with good finish and material just needs some work. If the door is more than 3/4 inch from the floor it will not work, the screw part is not long enough and screws directly out of the unit. I also want the (optional) rubber foot to stay securely in place. (Actually, a tangible rubber foot doesn't seem optional to me because without it, metal doesn't really stick to wood, tile, or carpet.) It doesn't stay, stick, or "jam," so it's fully detached. and you need to hold it while installing the device on the door, otherwise it will be easy to slip when you tighten the device.
