I've only tried it in a couple of doors, but so far it has proven too thick to shut the door. This product will only work with a door that has a bigger than normal gap between door and doorframe. It may work on other doors, I don't know, just not the ones I've tried.
I was a bit excited when it worked for one night. Two nights later it is broken. Not metal like the picture. Won't post reviews so quickly in the future. Huge waste of money
I bought as I lost my last one. Very happy with it as the old one came in very handy when staying in cheap hostels/hotels around the world. Gave me peace of mind and a good nights sleep and worked on all doors (bar one). Simple strong light and essential part of my seasoned travel kit.
I was a bit reluctant to buy a door lock at first ,considering that i had been looking extensively for a portable, non invasive and purposeful lock ,i m happy i found one.easy to put on and fits onto almost every door .just wondering what the red tape along comes for though,but anyways ITS A GOOD PURCHASE
