If only these where around when I was a teenager. The Addalock, portable door lock, lets you add a lock (see what they did with the name, there?) to pretty much any standard door. Parents keep walking in at… awkward moments? Live in a dorm? Travel a lot? Or just one of those silly people that like a bit of privacy on the toilet? Addalock lets you add a portable and temporary lock to your door, without any tools or screws, to your door so that you can avoid all those potentially embarrassing moments.
