I had a large dog for years, but when I lost him, I could not believe how vulnerable I felt at night without him. I thought about a security system, but they kinda take their time, and it does nothing at the moment when someones trying to get in. For years I slept with a chair under the front door knob. I do not know why I did not think of buying a security bar sooner, not just for my front door/sliding doors, but these in particular are portable because they collapse, so you can take them when you stay in Hotels, easily fitting in even a small suitcase. I have heard a few horror stories of thieves breaking in, or just "housekeeping" coming in at an unexpected moments. These security bars were the only ones with a wedge at bottom, instead of just a round base. It fits nicely against the floor, and the bar itself is very adjustable to the height of your door's knob. I tried to open the door when it was in place, and felt it would take a tremendous amount of force to get in. The bar is substantial, it is very solid and reassuring, not some toy aluminum thing. If nothing else, it would make a good defence weapon lol. It fits on doors and sliding windows, and has a round adaptor for that purpose. This is a great purchase, and now that I have moved from a townhouse to an apartment, no one can walk in on me without notice(you know what I mean renters). I slept soundly from the first night in my new place, very glad I bought them, and it was a reasonable price to pay for peace of mind!
