This was perfect for alerting when our toddler opens her door. The chime options are nice and the volume control is amazing. This is a great way to wake us up but not scaring us when doing so. Was easy to install and works across our house.

Just be aware this is a magnet8c interlock chime, not an alarm. It only plays for a few seconds and then stops entirely if door is left ajar. It is nice and loud if not hard of hearing though.

Great for alarming you when the door opens and shuts. It doesn’t continuously sound. Just for a few moments. We have it plugged in upstairs and we can hear it throughout the house. It will sound randomly even tho nothing was opened. I’ve had it plugged in for about a month and it went off randomly 3 times.

This is EXACTLY what I was looking for. Most devices the alert makes a very piercing sound. This actually has different friendly sound setting alerts. Chimes, door bell “ ding dong” and musical tones. ( even holiday! ) I care for a friend with dementia and this is great because it lets me know when she enters / leaves her bedroom and the bathroom. I bought the 3 pack with 2 plug in alerts that I can easily set up in different locations This is also great for young children to alert you if they open a door. Teenagers so you know when they arrive home safely at night if you fall asleep. For any reason to alert you if something opens!

Got this for my doors just incase my kid tries to leave the house. Work great and the sound is loud. Has multiple sound so we gave the doors different ones so we know what door is being opened.

Very easy to install and set up. We use it on freezer/refrigerator and front/back door We have a autistic son that will get up in the middle of the night. We dont like setting our home alarm so this unit fits. Cost is perfect. We set the receiver up in our bedroom and living room. It will wake us up with ease.

Works well with all the multiple settings. Has great noise range! Easy install. Only down side b is the security alarm may randomly chirp/ring.

Tiene varios tonos es fácil de instalar y me es útil para mi propósito aunque hace falta más explicación para fijar el tono escogido tuve q experimentar para lograrlo
