Super Heavy Duty Security Door Lock Bar Fully Adjustable Door Stopper Device for Home Defense for Residential and Commercial Use to Protect Against Forced Entry. Masterlock Door Jammer by Securadoor

Hi Will here, using my wifes family account. I never write reviews, however this product exceeded my wildest expectations. I have tested every door stopper stick available on amazon and home depot and all have failed miserably. Some collapsed because the locking mechanism could be defeated by wiggling the door back and forth (The white one with lots of holes available here and home depot). Others could be defeated because the grip at the bottom was a virtual slip and slide providing zero resistance (SecurityMan)This Securadoor door stopper is exactly everything I hoped for and more. Its easy to assemble (3 parts), easy to measure and set (60 seconds), and just freaking works. I unlocked my front door and had my wife use the securadoor, which was set on tile. The only thing that would hold it back was the securadoor itself. When I tested it this thing held my weight even I pushed against it as hard as I could. I had to stop because I was concerned the door would come off the screws and hinges before this thing security bar failed. Absolutely amazing.Then I tested it in my main bedroom. There we have thick 1 inch carpet. I adjusted the securadoor bar to fit that door frame and once again my wife placed it. I was able to push in and create a half inch of wiggle room but once the securadoor engaged, that was it. That door would not budge any further, even on super thick fluffy carpet. Literally as good as it gets.If you are looking for a great security door bar, look no further than this. I literally cannot think of anything else to add or improve, that's how great this thing is. Its damn near perfect. You get what you pay for and the quality is as good as it gets. As far as I am concerned ...this is the only real security door bar in the market. Everything else is just a sad imitation that will get you killed.This amazing bar works and will stop intruders from breaking past your doors.The only problem with this is that the stick works so good now i have to replace all the screws in the door hinges as that is now the weakpoint. A great problem to have.11/10 Extremely Recommend.

Very satisfied with this product, after using it, I no longer worry about someone breaking into the room easily, it is easy to use, and it is very strong.

Bought for my daughter but saw it in use this weekend. Very substantial without being heavy. Easy to put under and take away from door. She had a similar one she had bought when she was in college that was a joke when it was sitting next to this one. Definitely a great buy.

Easy to understand. Easy to set on all doors. Seems strong enough to discourage any intruders. Quick delivery within a day with prime. Good product.

My daughter lives in on-campus housing at college with four additional girls. The only lock on the apartment door is on the door knob - no deadbolt. They had reported a couple incidents of money being taken from their rooms and various items being moved around, as if someone had been looking through their stuff, but they did not have any proof that someone had broken into their room.Early one morning, at 4:30 AM, my daughter and her roommate woke up to the sound of their bedroom door being opened very slowly. Two males were standing in the doorway. When they yelled, the intruders ran out. Fortunately, no one was hurt and nothing was taken, but the girls were traumatized by the intrusion. Long story short, the college refused to add a deadbolt or security cameras (even though they have them in other buildings), so I purchased two security door bars as an alternative solution. The girls use one on the entry door to their apartment. My daughter has the second one for her bedroom door, in case her roommate is away and she's alone.The security door bars are very well made and sturdy. The girls have tested them by having people try to force the doors open, literally throwing their bodies into the doors, with no luck. This product gives them a better sense of security and allows them to sleep more peacefully in a situation where they are not allowed to add or modify traditional lock systems. I'm very happy with the purchase of this product.
