If you’re like me and have a large gap under your front door (someone could take a stick and just poke the leaning stick style door jam out), I recommend the Addalock. It’s small, perfect for traveling, and this lock is CRAZY. It’s so simple but the door does not move.

You can’t see it from the other side, either. It also cost about $20, and I can’t recommend it enough. Easy to travel with, too! Great for Air BnBs!
