Guard Dog Security Blocklock Portable Door Lock, Hotel Door Locks for Travelers Security, Tough & Durable, Apartment Door Security, Home Security, Travel Essentials, Easy to Use

Excellent product, low cost for easy piece of mind.

Works like a charm. Provided me security with the super easy installation. I had it tested with my family members. They kicked and pushed my door but it never budged. Although it depends on the door mine looks like this (wooden)

I've only used it one time at a hotel. It installed quickly and without any issues. When I was ready to leave the room, I unlocked the dead bolt and tried to open the door and the Guard Dog Blocklock held the door firmly shut with no movement of the door while I held the door handle in the open position and pulling on the door handle trying to move the door. It held firm! I will use this product each time I travel away from home and stay in a hotel room.

This is perfect for a woman alone at a hotel who is afraid of somebody breaking in. However the hotel that I stayed at had one built in so I never opened it and sent it back. It does look very sturdy though. Sure it's pretty easy to use and install.

These work really well. I have bought other ones like these that fit into the holes and don’t work with my door. These do!! They are very easy to put on and easy to take off. Extra security.
