Customer Reviews

The door brace works and gives me and my family peace of mind in our apartment building.
Ramsey
It is a great product, when not defected, and I would highly suggest returning it for another if you get a bad one, especially since they make it soo easy!

Trying to get into the door protected by one of these braces makes it very hard for an intruder to enter.

It arrived today and is going back to Amazon for a refund tomorrow. It looks secure when you put it in place, and feels secure when you test it by pulling inward on the door handle, but test it by going outside pushing on the door and you will be shocked at how easy it is to defeat. The rubber ears on the doorknob end are too flexible and bend out of the way (to the side and down) when you push on the door allowing the door to be very easily opened. The entire top rubber assembly also flexed slightly to the side on the metal pole as it was defeated. It's secured to the end of the metal pole about as well one of those rubber erasers that slip on to the end of your pencil. What's worse is that because the thickest parts of the pole, the top ears and the bottom foot, are made of soft rubber they were silent and made no racket as I pushed on the door. Furthermore since no metal parts hit the floor when it fell to the ground it landed very quietly. The rubber ears are what impacted the floor as it fell to the floor after being defeated, the rubber foot was already on the ground as it fell. I got in the door silently in less than 5 seconds. The tap from a lock bump would be the loudest thing you would hear. Get a puppy from the pound and a 12 gauge instead and sleep well, it's well worth the $400 total initial investment + dog food. I do weigh 240#, but I didn't have to push hard at all to get in. A false sense of security thinking that you would hear some serious racket as this thing got defeated is worse than not having it at all. What I was using before I tried this, and what I will go back to using, was a chair with the legs sitting inside some rubber soled tennis shoes to keep the chair legs from slipping on the floor.Read more ›

I purchased two Master Lock 265DCCSEN Dual-Function Security Bars about 4 months after looking at the various options out there (including the Mace Big Jammer.) The MasterLock Product seemed to function well and kept the door secure against some 'simulated assault' - I am 200 pounds and applied full/moving force with the door handle AND deadbolt disengaged.

Side note: all of these door jam type products perform well on a hard surface (tile/wood/linoleum.) They are NOT well suited to carpet.

Disappointment Part 1: One day, I returned home to find that my door jam (not engaged as I was away from the house) had fallen over (I keep it next to the door when not in use.)

Much to my surprise, the impact from the fall (slide) to the floor had caused the end of the door jam that notches under the door handle had SHEARED OFF! I hadn't really noticed before but the 'business end' of the door jam was PLASTIC! Needless to say, I was not impressed at this obvious design flaw.

Disappointment Part 1: I picked up the phone to call MasterLock... I'll spare the details but end result was as follows. a) MasterLock does not offer a replacement part for this plastic piece (despite the fact that it has a cotter pin for removal.) b) the customer service rep spent 10 minutes trying to convince me I had to return the device to the seller (they didn't want to bother with it.) c) when I basically forced the rep to admit that..."Yes...they do actually provide warranty service" - my only option was to mail the entire product (at my expense back to Masterlock.) d) She could only give me the return address verbally (sorry, I can't email that to you...

I put these things on every entry door of my house and love them. They give you a little extra time to react in the event of a home invasion type scenario. With enough force these can be defeated by an angry linebacker or a massive herd of zombies. Like I said, it will give you those few extra moments to reach your weapon and begin the process of eradicating the evil doers.

I have been very satisfied with this product. I put it the test and it absolutely did what it was made to do.

Someone tried breaking into my apartment door while I was home so I decided to purchase this device. I sleep much better because of this device. I have tested this out on a couple doors and it works great. I feel the door itself would break from the hinges or the door handle would break before this device would give way. This device would give me ample time to wake up, call the police, and setup a couple painful surprises for anyone that would make it past the door.

I feel that the amount of time, effort, and noise needed to break down a door with this device on it would not be worth it for a burglar. It is very easy to unarm when you are wanted to open the door, which would be important in an emergency such as a fire.

I saw the Master Lock version of this device and it is NOT constructed as good as the Mace version.

Apartment dweller. Can be defeated with some effort, but it does the job I need it for. This along with an extra interior keyed lock gives me peace of mind.

Good product if you use it on hard floor(tile or hardwood etc.)
Dirrections are terrible and leave you quessing as to installation. I tested the jammer,it can be breached but with a lot of damage and effort.
