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.

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!!

Nice product

we just moved to our new house and since our ring doorbell hasn't arrived yet we tried this and it's good. It's really loud and very sensitive. the size is perfect and functionality is very straight forward.

So firstly I received these yesterday and have gone about fitting 2x of the 4x received.Positives:• easy to install on your doors and windows with its self adhesive backing (time will tell how the adhesive holds)• its Loud! Like ridiculously loud !!! Certainly packs a punch especially for the size of it.• pretty compact so not really an eye sore especially if you have curtains to visually you hide itNegatives I found are:•if you haven’t got a flush surface like my rear windows don’t have, then you MAY FIND that the alarm will continuously sound as the alarm and magnet sensor are too far apart. (Pictured )• Be nice to have a different colour option for the casing to match your doors or windows ie white.Overall impressed and should definitely deter anyone unwanted that try’s to break in.

They’re quite large so do look abit of an eye sore. They’re loud. But the batteries can be a little lose so they keep coming away from the metal plates which stop them from working. It was a challenge getting them to line up and after installing around 3 weeks ago, we’ve already had 2 fall off. Still debating to be honest if it was a worthy purchase.

As a parent of a child with autism, safety is my top priority. These alarms are brilliant! They alert me instantly if a door or window is opened, which is crucial for preventing my son from wandering. They're inexpensive, easy to install, and give me invaluable peace of mind.

VERY VERY LOUD!!!!One of the ones came with a slight defect of making a short shrill noise when you turn it on but works fine otherwise and the other has no flaws. I ven still they are seriously impressive with their power and volume given their price being so affordable.
