I used it during my honeymoon around Greece and Turkey. I plan to use it any time I stay in an Airbnb, hotel, or anywhere I cannot travel with my pew pew. I tried pulling the door open as hard as I can and it definitely holds up. I like that it's adjustable and has extra rubber feet to adapt to most doors. Adds a little bit of piece of mind.

I picked up the DJ3 Portable Door Lock Brace back in August 2024, and let me tell you, this little gadget has become my ultimate travel buddy. It’s the best thing to happen to my peace of mind since I discovered noise-canceling headphones on a long-haul flight full of crying babies. First of all, the installation is so easy, even I could do it without consulting YouTube. Seriously, it’s like the IKEA of door locks—minus the confusing instructions and leftover screws. You just pop it under the door handle, and voilà, instant fortress mode activated! I felt like a secret agent securing my hotel room, ready to take on the world (or at least the room service delivery guy). This lock brace is compact enough to fit in my carry-on, sandwiched between my travel snacks and that novel I swear I’ll finish someday. It’s like carrying a tiny bouncer with you, ready to stand guard at any door. Whether I’m in a hotel, an Airbnb, or that questionable roadside motel (don’t ask), this little hero keeps me feeling safe and sound. The real magic happened during my last trip. There I was, in my hotel room, indulging in a true-crime documentary binge when I heard a mysterious noise outside. My imagination went wild—was it a ghost? A burglar? Just someone who got lost looking for the ice machine? Thanks to my trusty DJ3, I didn’t even flinch. I just sat back, sipped my overpriced minibar soda, and let the lock do its thing. Even at home, I’ve found a use for it. My cat, Mr. Whiskers, has a habit of barging in while I’m trying to enjoy some “me time.” Not anymore! The DJ3 keeps him out, and I get to enjoy my bath without an audience. In short, the DJ3 Portable Door Lock Brace is my knight in shining armor—or rather, my knight in compact, easy-to-install form. If you want to travel with confidence or just keep your cat at bay, this is your go-to gadget. It’s like having a little security guard in your pocket, minus the judgmental looks when you come back to your room with a second dessert.

I bought this to use when I travel. I wanted to give myself a little bit more safety while I am in my room asleep. Out of all of the similar devices that I have seen for sale, this one seemed to me to be the easiest to put on the door and take off. It also seemed to have the highest number of quality reviews, which is something I always look for when purchasing a product.. The device seems to be well made, and from what I have tried at home, it’s easy to install and take off. It also is able to maintain the door secure without slipping or sliding. I have not yet used it for travel. (I plan to do it later this year.). However, if the tests that I have conducted with it at home or any indication, I think it is gonna work just as I intended, and as advertised.

As a solo traveler, this device provided a little extra security and was not complicated to use after I figured out what I was doing wrong. Basically slide the foot under the door and press the back vertical piece at the hinge so that it’s flush against the door, then screw down tight. The foot doesn’t need to be perfectly flat to work. Traveling in Italy for 3 weeks last year and Portugal recently for two weeks (different hotels every 2 days) only one hotel could not use this device since the door bottom was flush with the floor. It worked on wood and carpet. During my stay, I’ve had maintenance knocking on my door and other hotel workers. This just helps with making me more at ease along with a do not disturb sign.

I followed the instructions carefully and watched online tutorials, but this product did not live up to its promises. The advertisement claims it will keep a door secure, but it doesn’t even provide a delay in the event of forced entry. It feels like false advertising. I highly do not recommend this product if you're looking for actual security. I don't understand why there are so many positive reviews. The people testing it out don’t actually show or try breaking in in their videos. Honestly, I’ve even got thick carpet, and it still doesn’t work as advertised.

This worked perfectly. My family of 4 went to Mexico for Spring Break. We stayed at a very safe resort, but having this helped me sleep better at night. We ended up with a suite and the kids bedroom was right by the front door. Our room was upstairs. If you watch the videos, this is easy to install and remove. In our case, the floor was tile and the door was wood, and I was able to get a very secure block on the door each night without too much effort. I’m sure it would work as well on carpet floors. It’s small enough to throw in the bottom of the suitcase (we checked, so not sure how this would go through security- it’s solid metal and strange-looking). Would definitely recommend if you’re a worrier.

The idea is great however, it does not fit in my doorways because I don't have large gaps between the door and the door frame.
