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

Simple to install and the alarm is loud enough to hear clearly from another room. Great extra security for doors and windows, especially for peace of mind at night.

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 .

It is quite good, does the job for our shop and it is very loud which is a bonus as it can be heard even when we're really busy. Only let down is that it starts malfunctioning after a month of use, bare this in mind if you're buying for your shop and the door will be opened very frequently.

These are great Easy to apply I use one for my window and the other one as a personal attack alarm when I'm returning from clubbing In the morning But haven't had to use it so far Highly recommend this product Extremely loud Has a siren mode and a door chime mode Batteries Included sealed inside the product

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

The alarm response is not as sensitive as I would have liked. After setting the alarm in place and following the instructions it took me opening the door/window fully before the alarm went off, if I opened the window/door halfway the alarm would not go off. However, the instructions are easy to follow, adhesion is strong and the alarm volume is okay.

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.

Alarm is very good and sound very well

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.

These alarm sensors are just what for extra security. I live in a townhome, and always nervous someone might get In through a window or door. The sound on this is super loud and really easy to install. It’s perfect!

Purchased for several tenants with small children. These are great devices that are easy to install.

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 !

These things do what they claim - make noise when opening a door. My only complaint (although others may find this a plus) is that the chime is a little on the loud side. While it makes sense for the alarm to be very loud, I wish the chime was a bit softer (a volume slider would be a perfect addition for customizing this). But they're pretty inexpensive and get the job done so overall not bad.
