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.
Steve A. Chambers Sr. –
Loud, easy install
Inexpensive door alarm. Easy installation. Loud
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.

Faulty alarms!
These are the absolute WORST save your money!!! First of all we bought these bc my peanut is an eloper. At almost 12 years old she’s figured howd to open all the child safety locks so I needed an alarm to alert when she got out and two out of four test runs the alarm just didnt go off then followed by it randomly having the alarm start sounding at 2:20 in the morning…. still in the same place it always was, but just going off for nonreason waking my autistic child who cannot fall back to sleep once woke and my neighbors. Save your money buy something better!!!
Darlene Hedges –

Arleashia –
Not loud enough to wake you up out of a deep sleep.
Low volume for a chime.

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.
