2 Pack Door/Window Alarm Magnetic, Wireless Security Sensor Burglar Alarm System Loud 90 dB, Shed Garage Vibration Entry Warning Detector, for Office/School/Hotel/Home/Store Security

Got them for my uncle with dementia to prevent him from trying to get out. Work exactly as they should.

Very good deal on the door security alarms. My mam has nurses coming in daily this makes her aware someone has entered her house.

Bought 2 pks of these , sticky pads were useless I cleaned the areas so no moisture or greese, but still some wood not stick oor within half hour fell off. The alarm bit either didn't go off or went off all the time in both on and off positions. And again fell off after half an hour, on two the springs to hold batteries were missing and on. The small contact pice again stick backs didn't work fell onto wool carpet backs cake off and metal brick inside fell out of plastics. Non of any of the 2 packs I bought worked sadly would not recommend wasted my money now have to buy elsewhere. Hate having to give bad write ups to any seller and I will try to attach a photo or video later to prove it but so far won't load.

Not a bad purchase for the price, very loud noise but the switch on the unit is a little flimsy

Really good in the nursery room. Everyone can hear them. Giving everyone that peace of mind when all children are about. Easy to install, good range of sound from it, going to wait and see how long the battery lasts. As definately getting a work out on the doors.

Not suitable for sliding doors or up and over windows

Superb … (batteries not included) high pitch alarm good value

Bought to put on my loft hatch after an attempted break in. Did the job nicely

Works great

Door and frame has to be totally flush together otherwise useless.. most doors and windows are not flush now a days..

I really like this product it’s very good and loud

works well no issues

Collant ne tient pas les deux morceaux doivent être très prêt l’un de l’autre donc difficile à installer et ne tient pas
