Wireless Door and Window Alarm Sensor 2 Pack 2 Modes Magnetic Window Door Burglar Alarm with 100dB Loud for Kids Safety Home Shop Security

These are great have them on doors and windows gives a little extra security. So easy to install and stick really well, slide off the bracket so you can change the battery with ease. The alarm is loud so would definitely hear it during the night or the neighbours would if you weren't home.

Having a disabled child who likes to open and escape from windows and doors, these have been a god send. Having the ability to switch between alarm, beep and no noise is really handy and this works well as a deterrent against escaping as well as alerting me to the unwanted opening of windows and doors. They’ve stuck in place really well, with clear instructions on how to fit them too. Total value for money and highly recommended

At first I had a few issues with the sound level, all I had to do was push the batteries in a bit further so that all good. Sticks really well and is incredibly loud. VERY easy to setup there’s no difficult technical stuff apart from having to unscrew it. Very high quality product would recommend.

Brilliant alarm , quick easy fitting and the alarm is really very loud , I live in an upstairs first floor lounge etc , and can clearly hear this should anyone access through my main entry door , I have ordered another set , as I also intend to pop one in my handbag for nights out , walking out aline etc as this is so easy to trigger off by a little switch on the bottom of the device . Well worth buying and it's a game changer for me after having recently encountered stalking from an ex partner .

Easy to fit, and does sound quite a loud alarm when triggered. Good value for a simple product.

DIDN'T WORK FOR OUR PATIO DOOR UNFORTUNATELY BUT MIGHT BE OK FOR FLUSH DOOR?

This was exactly what we wanted, well packed, easy to install and a reasonable price .

Topp und funktioniert wie erwartet, ist auch ordentlich laut.

Nella confezione sono presenti 2 sensori. Suonano veramente forte, ne ho utilizzato uno come allarme per la portafinestra, in modo che se mio figlio piccolo dovesse aprire la finestra in mia assenza, io riesco comunque ad accorgermene. L'altro l'ho regalato a mio cognato che lo utilizza come campanello quando viene aperta la porta del suo negozio. Ottimo prodotto al giusto prezzo

Muy fácil de colocar y muy sonora, es lo que buscábamos .tiene tres posiciones, muy bien de precio la verdad.Compramos dos.

We got these because our 2 year old has learned to open our front door deadbolt and the glass door we keep locked. I try to keep an eye on him 100% of the time, but using the restroom has made it difficult. I have a sneaky toddler. This has made me feel so much more safe and it only took him opening the door once for him to decided to NEVER do it again. I felt bad because it scared the daylights out of him. I have never seen him so terrified. But relieved because I don’t think he’ll make that mistake again. They are loud! You have a chime option which only chimes once and then it stops. That won’t scare anyone. But the alarm!! Loud and effective. It has even given me comfort at night knowing that someone won’t be coming into my home without us knowing it! Love these.

Points positifs : les piles sont comprises, le kit est très facile à installer. L'adhésif m'a l'air de très bonne qualité. L'alarme est très forte, je ne sais pas combien de décibels réels mais en tout cas suffisamment pour faire mal aux oreilles.Points négatifs : la '' sonnette '' prévue au premier mode est beaucoup trop stridante ! Elle est juste insupportable.Je pense que cette alarme va faire l'affaire. En tout cas pour ce prix là on a quand-même quelque chose de fonctionnel !
