120 DB Loud Door and Window Open Alarm Sensor 3 Pack for Kids, Dementia Patients Safety, Burglar Anti-Theft Wireless Security Alarms Keep Your Home, Pool, Cabinet, Business Safe

I bought 2 packs on this and it didn’t work. When you turn it on even there’s no sensor it’s making alarm.

Very loud, and straightforward, and compact.

Much better than a previous set I purchased. These are very loud. I use them for security on our doors with our autistic son who like to run, the noise is so loud it startles him into shutting the door and he doesnt run anymore. Stopped checking the doors even after a couple tries and being startled. Very effective.

Great idea for kids and elderly

Nice loud alarm but make sure you can attach it to your doors

We have struggled for years to get a full nights sleep, to keep our toddlers (2 & 4) in their room at night and out of things that aren’t safe, out of food they could choke on, etc. and we had unfortunately resorted to switching the doorknob to lock them in their room from 9pm-5am (the average hours they actually slept) and it weighed on my heart and mind heavily until I learned that not only is it a violation of several fire codes but could resort in CPS paying a visit. I did my research and found this alarm, I ordered it on Tuesday and it said it wouldn’t be here until Sunday. It got here Friday! I installed it, and realized that the doorframe sticks out roughly an inch from the door, so the magnet sensor wasn’t flush with the alarm. I didn’t have any spacers and it didn’t come with any, so I took a cardboard Amazon box, cut out 4 pieces that were the size of the alarm, taped them to together and made a spacer. It worked perfectly! A little tacky looking with my improving, but it does the job and that’s all I care about! Believe it or not, we laid the boys down at 8:30 (I also ordered blackout curtains for their room which got here Friday as well and hung those up hoping they wouldn’t pull them down and would sleep better)… after they heard that alarm when I turned it on, they literally went straight to sleep, didn’t talk to each other, get out of bed a single time, and I kid you not they stayed in their room until NINE AM!!! I’m shocked. Best sleep I’ve had in years. They opened their door this morning one time while I was nursing our youngest around 8:30am and immediately shut the door and ran to their bed! 🤣 I laughed SO hard and just pumped my fist in the air like a dweeb. I’m so thrilled! Now the only disclaimer I have- the package came with 3 alarms, I installed one in their room, one on the front door, and one on the back door. After I realized I needed a spacer for it to work, and made one myself and was reinstalling the one in the boys’ room, I pushed too hard on the alarm and sensor to make sure it stayed in place on the cardboard and ended up unfortunately messing it up to where it just made a crackling sound rather than a loud beeping 🤣😳😓 so I took the one off the back door and put it in their room, and I’ll order some more. So don’t push hard on them, that double stick tape has an extremely strong hold and doesn’t need a lot of pressure at all to stick good. Also if you have kids, place the alarm at the very top of the door where they can’t reach it. I am one happy mama and customer!
