I purchased this for my father who has dementia, and let me tell you it is very loud and is extremely helpful. When he tries to open the door and wander the alarm makes him alert and he closes it immediately.

Easy to install, adhesive quality is very good.

This definitely gives me a peace of my mind for living in a house w kids. I have this on all my doors. Very loud. Does the job.

Very good quality.item works as listed.

The media could not be loaded. 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!

Use to many batteries

These came packaged in such a small box. I was a bit worried however, they were individually packaged, were easy to install and are exactly what we need for the doors - alerting us if a small child opened it. This is used as a pool alert for small children and boy is it loud! We mounted it high on each door, so the adult can turn it off before opening the door, but the child cannot access the kill-switch. Perfect!.

Easy to install (but don't work on sliding patio doors, as door and jamb are not flush.). Quick, Inexpensive plastic device solution to monitoring exits until I figure out which code-exit devices to install. (Don't appear to be too durable - I don't expect them to last too long, but for the price, I am not complaining.) Loud enough to be heard in the next room - but not two rooms away.
