Can turn on/off at any time and easy to install/put on.

Finally got my husband to put hers on our windows. We have an alarm, however, the alarm goes off if the window is opened. So we purchased these to try to prevent it from getting that far. I like the fact that you can turn them on and off so you don’t have to worry about them going off unnecessarily when you’re home. They were easy to put up and you can adjust/move them around to work for what’s best for you. The sound is great and they are a little sensitive at times ,however, I will take that over them not being sensitive and not pickup on someone. So far so good. Will provide update if things change.

Extremely loud and responsive!

Very cool and inexpensive. Just what I needed. We always leave a window unlocked and always worry that someone will try to break in. These are very loud and will surely scare the piss out of anyone trying to break in. Including myself. I dread forgetting my keys inside and having to go through this window. Lol. But hey I feel so much safe. Thanks guys. I definitely recommend this product.

Loud!

Bought to keep my daughters and dogs inside the house! Perfect perfect perfect!!! My youngest is scared of the noise and my oldest gets caught every time she opens the door. No more letting the dogs out! This was absolutely perfect for my family. Was super easy to install and did allow a little gap cause my door and edge are uneven.

Very loud and easy to install.

Love these! My husband works out of town a lot so these were a great addition to our security system. They were so easy to install and work so well! I am able to hear them downstairs without issue and my neighbors stated they heard the noise as well which is added security. We were able to put on our doors and windows! Plan to purchase more. Very reasonable in price and great in quality. Very easy to install and move as needed!

Safety? Protection? Or just want to be alerted if opened? Here it is!

Easy to install! Works great for several reasons :-) now I just need to order more for every window in the house.. no need to worry if someone is sneaking in or out (uhh hmmm teenage parents) no worries about intruders.. I need more! Haha

Easy to install

I like that it only took a few minutes to install as it’s just peel and stick. Just make sure that the arrows match up between the two devices. The siren is loud when it goes off and no matter what room of the house I am in I can hear it. It has an on and off switch on the side so if you decide you want to open your window you can.

My special needs daughter will stay safe because of the door alarms!

I have a special needs daughter that does not understand safety. She also has no fear. We have had to be super vigilant watching our front and back doors to the house because she always tried sneaking outside without permission. These door alarms allow for yet another "barricade" (safety measure) to keep her safely in the house. She cannot reach where we placed the alarms, therefore cannot shut them off without us knowing. She also HATES the noise that the alarm makes, so that also deters her from opening the door to let herself outside to play without our knowledge. I am not saying these alarms are a stand in for supervision, but with safety being of our utmost concern, these alarms serve as another set of eyes and ears to alert the family that the door has been opened.

Great w/ Kids

I live with a roommate and his 2 year old daughter. She is learning how to unlock doors and open them. These are invaluable in knowing when she was getting into a room she shouldn't be in or wants to go outside. This sound scares her, so now she doesn't open a door unless we tell her it is ok. Hopefully it will also deter any intruder. Great product for peace of mind!

Easy loud alarm perfect for our family

I am so grateful I found these alarms. We live on a busy street and have doors that open very easy if they are not locked. With two small toddlers this is not the ideal situation. These alarms were super easy to install with no permanent fixtures (important when you rent) and they are loud enough to hear throughout the house. I have one on every exterior door and it really provides me with peace of mind. A bonus on these alarms is they are so cost effective.

Worth the money

I received this nifty, easy to install gadget today. I wished I had come across this thing ages ago. My Mom has Alzheimer’s and is a wanderer. I lock our screen doors but occasionally she figures the lock out. I haven’t been able to leave her alone in any room that is not within my earshot. Well tonight I popped one of these alarms on my front door and baca bing bada boom! This alarm shrilled so loud I bet the whole neighborhood heard it. My Mom hasn’t wandered any where near that door so far on this day.
