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 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

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 .

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.

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

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.

Very good and very You can hear them

Very good value easy to set up ,has sticky pads, so no drilling or screws to apply, but be 100% sure before ,sticking as not easy to remove ,which is a good thing ,look carefully when fixing ,one part the smaller one is a magnetic, and will be slightly different, on different things so on front door larger part on the door, and windows other way and patio doors different, but easy to figure out ,the noise is either a very shrill very loud noise ,or very loud beep ,and definitely gave me piece of mind ,run by battery, which with these are included ,with this set but not with all so check that

Excellent window/door alarm. Clear chime and loud alarm sound. Easy installation and very happy with appearance and function. Would recommend. Chime is good to alert kids opening a door to come in or out.

Super Preis-Leistungsverhältnis. Der Alarm löst zuverlässig aus, die Batterien sind sehr langlebig. Kinderleichte Montage und es wird einem direkt ein sicheres Gefühl vermittelt.

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.

I originally used a different brand for a "wondering at night child". The other brand failed within a week and we woke to my 4 year old OUTSIDE at 2 a.m. even with high locks and said alarms in place. We sent those crappy ones back and I opted for these. We are on our third month of this brand. I couldn't be more pleased. We have 3 doors that can take you outside, and two floors. So having 3 sensors and 2 receivers works perfectly. I listen every single time we open a door. And it works every time. Like - EVERY.SINGLE.TIME. these (on 24/7) coupled with an 'at the door screeching alarm' set at night, and high locks. This mama is finally sleeping. And my son has been able to go back to his own bed. I am so grateful for this product.

It’s loud enough to give anyone second thoughts, before proceeding further. Hubs put one on front door, one on back door, and one on bedroom door. If the bedroom door is opened, you WILL definitely wake up, giving you time to grab your loaded gun off the nightstand!! I love them!!!

I was very confused when I bought these. There alarms have 2 pieces. The 2 pieces have to stay very close to each other. So one will go on your door and the other one o. Your wall. When it is pulled apart the alarm goes off if you have it set. It has 3 modes to set. Alarm (a super loud one) then the middle option is like an alarm on your phone, and then then there's off. So you have to set it everyday for it to work!
