Very good product doe's the job also added bonus keeps the children away from the window no more fingerprints on the clean window's they don't like the noise very loud.i have recommended to family.

slim and very loud alarm which hopefully will have the desired effect of warning any would be intruders. Pleased with my purchase

Have had these on my windows for about 4 months. Pros: - reasonably loud - ear piercingly loud if in the same room, but sound doesn't travel that well - behind a few closed doors sound does decrease quite a bit. Will do the job of scaring people away though I imagine. They can be heard from outside/opposite side of window. - good longevity (so far) - have been on my windows, and have been turned on and off lots of times, for 4/5 months with no need for battery change, and have remained same volume. - good that it beeps at you to tell you that it is on - they don't all do this - means that you can turn it on and be sure that it is working. - on/off switch - useful, especially if it is getting set off too easily/you know something is going to set it off/it has gone off and you want to reset it. - good that alarm turns itself off after 30 secs - good adhesive - had no problems with them falling off, even the one above sink in kitchen. Cons: - very sensitive - both a good and bad thing of course. Sometimes banging something hard when doing washing up sets it off (alarm is right in front of basin though tbf), or when bee or something flies into window. We tend to turn them off when we're in, and turn them on at night and when we're going out. - cant tell if its still working without turning it on/off - eg. they could have made it so LED would flash when on to let you know that it's on (would use battery though tbf). You can always turn it on and off if you want to check anyway. Happy with purchase - good quality, functional, good value. Would recommend.

Good, loud, and easy to install, come with battery, and stickers.

These are loud. I installed in my garage which has four small windows.I set the alarms. I shut the garage which triggered the alarms. The noise was painful. Had to open up and switch off each of them... so yes they are good but not for what i was intending to use them for. They will wake the dead annoy your neighbours and make the intruders/my ears bleed everytime the door is opened or closed. Back to the drawing board. Would strongly recommend

I bought 4 window alerts which mentioned a warning sticker that helps deter theft, but when I open them no sticker is attached! Therefore, it is so disappointing.

Very easy to fit and operate. Worked well when the panel was banged. The siren should prevent any future attack. Very pleased with the product at the price.

Very easy to setup alarms and I’m sure that they would help to deter any would be burglars from breaking into your property. I bought 8 with the intention of putting one on each of my windows. I just tried them initially in the living room to see how I got on. Unfortunately they haven’t worked for me as when my puppy barks loudly at something outside she sets the alarms off in whichever room she’s in. Sadly still have 3 packets of unused alarms that I will now have to either sell or give away.

Installé sur toutes mes portes et fenêtres. Interrupteur de mise en route (off/on). Parfait quand je m'absente. Mes voisins entendent la sirène et peuvent vérifier ce qui se passe.

Buon prodotto

Sensitive, triggered by loud barking of nearby dog or dropping of heavy object. Bad batteries included.

Sehr einfach zum Montieren und sind sehr laut.

Mejor imposible!!! Lo pones detrás de la puerta y con la vibración de meter la llave suena. Muy efectivo de cara a ladrones y okupas.
