Door Window Alarm 4 Pack Noopel Home Security Ultra-Slim Wireless Magnetic Sensor Burglar Anti-theft 120DB Alarm with Batteries included - DIY EASY to Install (4)

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 item, easy to fit and very loud when activated. I have a parent with dementia and we have them on the front and back doors so we are aware if they get opened. Would definitely buy again.

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.

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 alarms are very loud, frightens the life out of you when you open the door. These are great intruder alarms as you will certainly here is someone opens the door.

Batteries don't last long, cheap and cheerful but I wouldn't buy it again. Sticks well, hard to remove.

Great item, straightforward to use, great deterrent, seller has great customer service, and I highly recommend

So far I have bought two packs of these one for my house and the other for a relative after they had someone try to get into their house. Plus side; they are loud and you can hear them at the opposite side of the house, easy to assemble. Downside is that for them to be effective they need to be side to side so if you have a back door that as a recess you can struggle to align them. To achieve this my relative managed to attach them to a piece of wood he fastened to the door so they could be aligned.Overall I feel safer and so does my relative.
