These are excellent alarms, definitely loud and would send any would be intruder running, good quality, easy to attach and position.

I recently purchased a window/door alarm, and let me tell you, it has exceeded my expectations in terms of both loudness and effectiveness. This little device truly packs a punch when it comes to security! First and foremost, the alarm's volume is off the charts. Once activated, it emits a piercing sound that is impossible to ignore. The decibel level is so high that it can easily startle anyone in its vicinity, including myself! There have been a few instances where I accidentally triggered the alarm and found myself jumping at the sheer intensity of the sound. Rest assured, if there's an intruder or an unauthorized entry, this alarm will certainly make them think twice about proceeding any further. The effectiveness of this window/door alarm is truly impressive. It serves as an excellent deterrent, and I feel much safer knowing that my home is equipped with this device. It is highly sensitive and reacts promptly to any tampering or forced entry attempts. The moment someone tries to open a protected door or window, the alarm blares, alerting everyone nearby and notifying potential intruders that their presence has been exposed. One of the standout features of this alarm is its simplicity. It is incredibly easy to install and requires minimal setup. The adhesive backing allows for hassle-free attachment to any door or window frame. The compact size and sleek design ensure that it doesn't detract from the overall aesthetics of your home. While the loudness and effectiveness of this alarm are undoubtedly its greatest strengths, it is worth mentioning that it might not be suitable for individuals who are easily startled or have sensitive hearing. The alarm's intensity can be overwhelming, even for someone expecting it. However, if you prioritize security and appreciate the reassurance of a powerful deterrent, this alarm is an excellent choice. In conclusion, the window/door alarm I purchased has proven itself to be an exceptional security device. Its extremely loud and attention-grabbing alarm, coupled with its effectiveness in deterring potential intruders, make it a worthy investment. Although it might startle you at times, the peace of mind it provides is priceless. I highly recommend this window/door alarm to anyone seeking enhanced home security.

Great alarm. But the adhesive loosens after some time that's due to wear and tear.

After having an attempted burglary at our household and spending countless nights not being able to sleep, listening for any suspicious noise and looking out the window constantly. I decided to upgrade our security measures and along with various purchases I came across this product. While reading the reviews, I was dubious and unsure of what to expect. My concerns were; Practicality (would they fit my doors? is there too much of a gap? will I get false alarms?) Noise Level (will they be loud enough?) Adhesion (will they stick or do I need to order better sticky pads?) Battery Life (how long will the batteries last?) Now I have purchased them, I can tell you that; They will fit ANY door/frame/window set up. The noise level is EXTREMELY loud which is great. The adhesion is perfect as it is supplied with 3m pads. In terms of battery life, batteries are supplied to start with and we leave the alarms on 24/7 and still I personally doubt they will be needing any change for months to come, but when they do, it has a low battery warning. I actually bought upgraded adhesion pads thinking that they would be required from reading previous reviews but this is incorrect, the ones supplied are fantastic. I believe the other reviewers may not have cleaned the surface before sticking down. This is hands down, the most ingenious, cheap, initiative and best product I have ever bought on amazon. I feel the company is selling them for too little. I understand you may think that obviously they are no comparison to the likes of a full house alarm and upgraded locks etc. But the job that these do for the price of £20 and the sheer practicality. Please tell me where you can get better! It’s not until you purchase that you will see just how good they are. I thank the person that created them. BUY BUY BUY BUY BUY!!

These are great. Very loud and should out off any intruder. Easy to install as well.

So I was recently burgled and bought these as an affordable option to add an extra layer of security to my home. The installation was very simple, my only concern is how long they will stick for. It would be a nice addition to be able to screw them in place. They are very easy to disable but do serve there purpose to frighten any intruders. Overall an affordable option to add to an existing security system. Would not advise to just have these alone as it is not enough to deter thieves.

I like this product a lot. I've only had them for about 10 days, but they seem to be doing the job well. I've had something like this before, in the distant past, but I bought those for a pound in one of those shops with all sorts of cheap household stuff around the corner from where I was living at the time. My locks often get picked at my current address, in spite of various steps that I've taken and it's been causing a lot of stress, in spite of the fact that the lock-picking may (or may not) be done by anonymous pranksters. It was time to add a major deterrent. I also recommend these alarms to people I work with, to increase their security at a relatively low cost and without complicated installation procedures. They arrived promptly, packaged individually in bubble wrap, inside a small cardboard box that could have done with a little bit of sticky tape to keep it closed. As it arrived in a large envelope with other items, that was not a problem, however. Nothing had escaped from the envelope. Each alarm has three button batteries in them; I expect they'll last for a long time. For obvious reasons, I'm not including photos or videos.

Why did you choose this product over others?: Wanted an alarm that was simple to set up and use. Functionality: Very easy to stick into place with the pads provided. On and off switch cant be any easier. Makes a fair racket when it is functioned. Good for doors and windows. LR44 battery's x 3, do not know how long they will last, would have preferred 3 x AA batts instead.
