Great Added Security for Travel and Home
The Master Lock Sliding Door Stopper and Door Security Bar works great and gives me extra peace of mind when traveling and at home. It's easy to adjust, feels sturdy, and takes only a few seconds to set up. I like that it works on both hinged and sliding doors, making it very versatile. The folding design makes it compact enough to pack in a suitcase without taking up much space. It feels well-made and secure when in place, and the non-slip ends help keep it from moving. Overall, it's a simple product that does exactly what it's supposed to do. Highly recommend for anyone looking for an extra layer of security.

Don’t hesitate, buy!
This door stopper is amazing! Strong, heavy duty, easy to use, and really secure. I’ve had it for a couple years now. Great value for the money. I live alone in an apartment and don’t have a deadbolt, so wanted something for an extra layer of protections. It’s weighty enough to be used as a weapon if needed too 😂 I love it!

Amazing! Everyone needs one of these
I wish I would have had this when I lived alone (as a woman) in college, it would’ve given me such great peace of mind. Even if you aren’t worried about home security, this is a must-have for traveling or staying in unfamiliar places. My partner and I moved recently, and it’s not exactly the safest city in the state. We have an electronic door lock that we can pretty much only access by an app on our phone. I bought this minutes after I listened to a true crime story about a woman who had an electronic door lock on her apartment door, and a security officer for her building simply googled how to bypass the lock one night, entered her apartment, and raped and killed her. It’s a fantastic security tool for the price, I recommend everyone have at least one of these, especially if you’re a woman. As I showed in the video, the door doesn’t budge, even if I pull on it hard, and I have the bottom secured to a (admittedly long) rug too. Now if I’m alone in the apartment for a few days, I feel totally safe because of this. In fact, my boyfriend liked it so much he has started putting it on the door before bed each night. It’s really easy to set up and really easy to take down. I love that it folds up, too. Wish I could have gotten it in another color than white, but that’s just my personal aesthetic. I don’t know why I waited so long to buy one of these. You will absolutely not regret this purchase, and it could quite possibly save you and your loved one’s lives.

Quality and use
I’ve been using this for a long time every night behind my door Believe or not if somebody wants to break my door come in this probably won’t last that long, but I would know before that I’ll be ready for it. I doubt anybody can break through it but if they do, I’m waiting.

Effective
Used to support an apartment door with a wood veneer floor. Its easy to setup, put in place, remove. In place it’s sturdy and better than the usual small lock used on hotel apartment doors. I bought this as a gift for a relative who lives alone. Good value.

Works well
Low tech and gives peace of mind overnight. Light and easy to set up in 5 seconds and take away in the morning. Nothing will stop someone willing to break down the door, but makes it much harder to get in without making lots of noise to warn us to take actions. Folds up so we might use for hotels.
