Portable Door Jammer: Customer Reviews
“Portable and super easy to install. Just about the only negative is that I can see it not working on some doors that don’t really have a gap at the bottom. Like many hotel room doors for example.”
“LOVE this thing! I’m a teacher and sometimes just need to get things done on my breaks and during my lunch hour. My classroom doesn’t have a lock on it, but this effectively acts like one. If I don’t use it, I’ll have a steady stream of people coming into my classroom just to hang out.”
