Perfect Window Alarms
This is perfect for women who live alone. It was very simple to install and took like 5 mins. And it works! The alarm is very loud and you def will know if someone opens your windows.
Annie –
Nice loud sounds
So far this is working great. They were easy to install and the three sound settings are loud enough to hear when my kids open the door from anywhere in my house.
Sarah M –
Works well for the price
This product does exactly as advertised. They are easy to install and VERY loud. I’ve only had for about a week but so far they seem to be functioning well. I have these only my doors and windows. They work perfectly for the door but I do wish they were just a little bit narrower to fit in the window better. Overall they work great especially for the price.
GG –
Quality door and window alarms at a great price
Great value for the price. Small alarm for windows and doors. I used on sliding glass doors and windows. The adhesive is high quality – it sticks and does not move. Volume is loud and adjustable. It can be switched from alarm to chime. Batteries are button batteries and are included.

Great, but be careful
It works as intended, however I have to warn people not to install this around kids/babies/toddlers/pets and if you can wear ear plugs because it’s been four hours and my ear won’t stop ringing since i briefly heard the alarm. It’s very frustrating and is showing no signs of stopping.There is no doubt I can hear it from my window well in my basement to my third story even with a fan. It sounds very legit and if I didn’t know better I would assume it was hooked up to a professional security system. I believe my neighbors would hear it in their own house, it’s that loud.This would be great for people with curious toddlers or kids who you fear might sneak out the door. You can set it high and they can’t reach it, the sticky tape is very impressive and strong.It works, gives me peace of mind.

Some won’t work
Some didn’t work, they’re loud and setup isn’t quite clear

Works Great for Me!
This product does exactly what its intended to, and that’s to startle intruders, or notify the owner of surprise entrances or exits. Its loud enough up front to startle anyone that isn’t expecting it, and hopefully cause the intruder(s) to run away in fear. If you are upstairs, or are many rooms away with loud background noise, it could potentially drown out the alarm. So do not only rely on the noise of this alarm for safety, please please please always be aware of your surroundings and be safe and cautious. Otherwise this product is great, works simply, and is easy to install with adhesive attached to the back of each device. It also comes with batteries in each device, but just go ahead and order extras so that in the future you always have them to replace dead ones right away. Watch the illustration video provided, and you can get a good grasp of what this device does, and if it’ll be effect for you!

Not as loud as expected.
VERY easy to install. Not as loud as others I’ve purchased in the past. However, it does give you options on your sound preference

Love them it is great when l have my grandson at home. I have a pool in my back yard and it stops him from going out the patio door.
Amazon Customer –
Very difficult to use if there is any kind of trim around the door. Works well when there isn’t
Angie –
Used on my doors and windows after an attempted break in. Super loud, there is no volume control so you can turn it down and I swear it would wake up the dead.
