Portable Door Lock Brace for Home Security and Personal Protection (DJ4LD – Lockdown (XL Edition))

Works exactly as described. When placed directly below the door knob and screwed down properly — the door did not budge open when force was applied. I have used the “stick” type door stop but it stopped working in less than 2 months after the “foot pad” i.e. the part in touch with the floor (mine was vinyl tile) wore out.

No need for any photo or fancy movie to review these. These things work, they are very easy to install and very difficult, if ever, to overcome; door hardly moves while in use. I struggle to admit that anything made in China fancies me, but I am going to purchase again another set for my daughter who is an elementary teacher. Yes, that thing will definitely be handy if needs be, the "lockdown" name is quite appropriate. I do not know the material but it is strong enough to give enough minutes to be "prepared" inside a house or apartment, and also to dissuade an 'intruder' from spending interest, time and effort to overcome its 'protection'. Watch the other reviews for how to use it if you need. The instruction booklet included is written for 'supervision' which I do not have, but I can use my own logic and that was enough to learn how to operate the main item, for the extra rubber gadgets go online.I am 100% satisfied and I do not care for the price (you receive two anyway) or other brands, I will purchase a second pair right now (I received them today). Whether you call 911 or 811 these things will give you precious time on inside doors too!

I've had several floor anchored models in the pst that worked great but were a bit difficult to engage each time. My new house prevented me from anchoring through the concrete floor so I decided to give this one a try. Very good design and it works as described. I'm happy with the product and will order another.

Why did you pick this product vs others?:This product doesn’t work on doors with normal household thresholds. Screw length is too short. Pivot mechanism prevents tight fit. Discovered too late and missed return window, so we’re stuck with them. Expensive mistake. Caveat emptor.

It works well especially for French doors. I bought the bigger one. My main complaint is the ridiculous price. I would have bought a couple more but I don’t think they are worth $50.

My wife is a school teacher and this gives her peace of mind. Great to take to hotels too, since we’ve experienced someone walking into our room one night!

Can't be applied quickly, so it's not safe for emergencies. There is a specified minimum door gap in the description, but it also doesn't work in a gap of more than half an inch. In my experience, it only works reliably when used with a second barricade device. It definitely can provide increased security, but not in an imminent emergency and not as the only doorstop device used.

I purchased the DoorJammer - XL heavy weight Lockdown Edition. I travel all the time and safety has always been a serious concern of mine as I stay at various hotels and rental properties. This purchase has been a game changer. It is extremely EASY to install and uninstall the DoorJammer. Once it is PROPERLY installed, the door cannot be opened from the outside. It even comes with its own bag for easy travel. Buy immediately!
