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

May not be applicable in every door configuration, but device is effective for the most likely use scenario, especially hotel room doors, or front doors with simple doorsill to floor relationship.

Easy to use

Works a treat. I wasn't expecting it to be so solid. But it didn't move a millimeter, stuck like glue to the floor! The door flexed and bent a little, and I think the hinges would be ripped out of the door frame before this gave out. Worth every penny for the safety and security of your family and home. Easy to fit, only takes a few seconds. I am very impressed!

Bonjour, Objet utilisé lors d’un séjour à l’hôtel. Très grande facilité à mettre en place et très efficace. Robuste dans sa fabrication. Les différentes cales en caoutchouc livrées avec le bloc porte doivent être utilisées avant le placement de celui-ci. Ne pas oublier ce détail sous peine de faire remonter la porte dans l’encadrement et au pire la coincer en fermeture. L’objet a été utilisé sur un sol stratifié et le maintien est parfait et ne glisse pas grâce a l’embase recouvert d’un caoutchouc. Ne pas mettre sur un tapis.

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.
