Review: Powerful and Effective Window/Door Alarm That Packs a Punch! - 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.
Review: The best thing I’ve EVER bought on desertcart! Seriously. - 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 desertcart. 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!!

## Questions & Answers

**Q: Does it work with sliding doors?**
A: I would say yes - the sensor and magnetic contact are separate - when sticking on try without removing the adhesive backing on either the magnet or sensor to get the correct position - when you have mark lightly with a pencil and then apply - mine work great and still give me a shock (with the noise) when i forget to flick the switch off. Hope it works well for you

**Q: When i installed the alarm on my door, i switched it on and it is continously making the alarm sound?? What do i do to stop it?**
A: Hi Ashley, possible because the gap between the alarm and little strip is larger than 10mm.
if so, the only way to stop it is to switch off.

**Q: Do both sections have to be at the same level as my door has a trim/lip which is 1.5cm higher**
A: They have to be level and in line I glued a piece of wood on frame to line up works great

**Q: Battery life since august 21 I have changed the batteries 3 times .The alarm has never been triggered, except when installed**
A: I can only say that my alarms are all working OK  and the batteries i have never changed since arriving about 4 months ago. Do you check they are working on a weekly period. If you have a spare 1 then leave set up in your home side by side. And check to see what's going on...

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