    • The DJ3 Portable Door Lock Brace: My New Travel Sidekick!
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. ... show more

    • Used every European hotel
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. ... show more

    • Know its limits
The efficacy determines the circumstances! This would not work on my front door bc there is a 2 inch ledge that this could not fit. However, it works great on my back door. You have to position it correctly and twist the lock all the way down to where it's tight. It does work very well - I could not open the door without it being compromised. However, we use this door somewhat often and it's a pain to constantly untwist and reposition when we leave and at night. That's something to keep in mind. In my experience, it's best for traveling (knowing it won't work in every circumstance) and for doors that you don't frequently go through. This is great while we wait for our security door. ... show more

I really like the door jam I have a double front door and this product helps keep the second door tightly secured I recommend it. I would imagine the larger version would be great for a business or a classroom door!

    • Not what I expected.
Nice idea but hopefully this is more of a prototype for an upcoming new and improved version. This cannot be used in any community in door in America. I’ve tried it in the front door, kitchen door and bedroom doors but it does not work anywhere. Tried it in a hotel room door and nothing. It does not slide under nor does it hold and stay in place. Don’t waste your money. ... show more

    • Not quite meet expectation
The unit is sturdy but the top rubber strip (where it makes contact with the door) has already faded after a few uses. Also, the metal lock brace foot which holds against the floor tends to slip out slowly after a few hours. A few times the brace actually came loose before I wanted to remove.

    • Easy Travel Extra Peace of Mind
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. ... show more
