Will these really prevent a burglar? Has anyone had any experience with their resilience under force?

I couldn't get these to stay attached to glass. I would not depend on them for safety. I think they are a good idea, but I wouldn't recommend them.

They are really good. Rhe dior can't be opened. Tje burglar could always just break the glass if they are that determined

I don't think it would deter them if they "really" wanted to get in. These can be pried open with a butter knife & there'd be no sign that they'd been opened.

No, the alarm is basically a deterrent to a thief. When the security is breached, the alarm does sound, but not loud enough for even a close neighbor to hear. I guess it amounts to a scare tactic to a thief looking for an easy break- in. Hope this helps

This product is credited for preventing a break-in in my neighborhood the other day. Mid morning on a weekday, while the wife was home, they tried to kick the door in but couldn't. Several other homes in the neighborhood were similarly targeted, same MO, in the last several months. They got in to those houses.

No, just showing this device would not deter anyone who breaks into your apartment, you have to make contact with the invader to shock them. I would suggest the writer purchase a Taser gun or explore other defense options that can be applied from a distance .

No! This lock has worked wonderfully at our house! We haven't had any break ins since we installed it, while prior to this lock we had 4. We actually did have an issue with our landlord (I live in a college town and leases are yearly) about changing the doorknob to a locked code. He was worried that in an emergency he would not have access to our house. (Trust me, I lol'd at what kind of emergency would require him to get into our home..) But to appease him we set a "User Code" for him and his maintenance crew to use. Installation was easy & this product works great. All of our neighbors have installed it as well. No!

In my opinion YES, it will prevent that. It is double bolted and secured to the side framing of the door. With a past in public safety, I researched this quite a bit because in our new home we can not use a simple pin to secure the door over and above the cheap latches that come on sliding doors. When I researched this type of lock and passed it around a few police friends we were all in agreement that this would ultimately keep the door attached and unable to be removed from the tracks as normal access with a crow bar or heavy screw driver would allow. I highly recommend it.

Do you mean for security or just so they don't move? I have not needed to secure them. They just stay on the shelf... Maybe some earthquake putty if you find it is slippery.If it is to prevent theft - I don't know.

It might if the door was jarred or thumped hard enough, but I suppose if they were able to do it gently, then no. Just my guess, haven't tried it personally. :)I've triggered mine mistakenly on occasion by bumping it or hitting it with the dog's fetch toys, but it's smart enough not to sound when the sliding glass doors are opened.Ultimately I think these alarms are designed for sounding upon breakage of the glass, they are definitely a good deterrent in that regard, but for covert entry through doors being opened(or removed) they probably won't fare so well, unless it was done in a forceful enough manner.Hope this info helped!

I concur with the two previous answers. I got them to block out background noise on airplanes and confirming the comments from Julie and scott, for this they work exceptionally well, blocking pretty much all background noise . While I've not tried them in a light industrial setting, I've had lots of experience in that kind of environment and believe they would work well. A word of caution, they are so effective that they will likely also block warning signals in that kind of an evironment, including trucks reversing, and others. USE CAUTION!

My is at the entry of my house - also not such a great idea although it will alert you if the power is disconnected from it and there's a battery back up -- a burglar could still have enough time to take off, unplug it, and remove the chip before the system has time to react or sound. I think the best thing to do (and I need to do it myself) is maybe install some screws around it so it cannot be removed from the wall too easily or too quickly. I'm worried if move it far from the entrance or "hide" it -- it will be found anyway as soon as the alarm sounds or I won't have enough time to get to it and turn it off before it sounds. The only issue I see with this alarm is that a burglar w/ half a brain could destroy it before it was time to do anything more than send you text message that the power has been disconnected from it -- but it will also send you that message when there's a power outage.

I have used them successfully to block off noise from heavy stompers living above me but they have carpets. I would think it would work because it also takes the edge off of street noise since my room faces the street which has a streetcar going by frequently. Sometimes they almost block too much noise because I can't hear my clock radio's music turn on so I pull them out of my ears slightly. They bring me peace and I can finally sleep soundly!

I don't believe that they do. This is purely a mechanical lock - if you mess up entering the combination, just twist the dial counter-clockwise and try again. This is unlike an electronic safe w/ a "lock out period" after a certain number of incorrect entries, and would allow somebody to brute force guess a combination more quickly. However, the trade-off is this is not susceptible to battery or electronics failures (both of which I've experienced w/ the electronic safes.) Personally, I prefer the trade-off of better reliability to potentially more secure against brute-force guessing. Keep in mind, NO small, portable safe (or even big installed vault) is truly 100% secure. This is a very well built and solid unit, by the way - great for travel and/or vehicle storage.

It didn't work to deter my teenagers, as they pulled hard and the "foam" padding ripped away from backing. That said, I had a "lock" on there that doesn't really look like a lock and they weren't paying attention and just grabber and yanked the door as usual (the door sticks, so we all used to giving it a good strong pull to open it under normal conditions). But to deter burglars?....just depends on how determined in burglars is. All they'd need to do is slip a sharp, thin knife between the metal piece and the door and cut the foam backing. Would I risk 1000s of dollars of food if I was using this on a restaurant fridge? No, I wouldn't, I'd figure out how to get some holes of some sort drilled into the fridge instead. Hope that helps! Good luck.

you might try padlocks with straight lock pins they come with various size pins. You can't stop a determined thief but you can make not worth the time.

That's a question for the Master lock, not the end user, however, no lock can keep any expert out. This device is meant as a deterrent, and that it does very well. The problem with the door, is that it takes a mere second to steal. Not the case if he has to find a key that fits the lock. The idea with thieves, is to get away fast without getting caught. The deterrent prevents a quick getaway.
