Set this up to be an alarm on my toddlers door so if he got up at night we'd be aware. Does exactly what I wanted and the volume adjustment and tons of tone options really make this a great option over simple door alarms.

I love this door chime! It was so easy to install & I love that the two door pieces don't need to touch for the senor to work! There's over 50 different chimes/songs you can choose from. I've had this up for a couple of weeks now and they've stayed in place with just using the sticky back instead of screwing them on.

Works great. Good buy.

This was really easy to set up, and works great. I have it set up on my toddler's door, and atm they just find it hilarious to make it go off and on again, but it also lets me know when he's up from naps and if he gets up in the middle of the night. I love giving my child the freedom to come and go whenever they wish, and also being aware of where they are helps me know they are safe.

Excellent, easy to set up, works like a charm!

Best if you have kids who try to open doors all day long!

I take care of my mom with dementia. My studio apartment is attached to the garage and separate of the house. This allows me to know if she decides to go outside, or if someone opens the door. Along with the baby monitor, I can feel safe knowing she still has her independance and I have a little privacy as well.

Bought this cause I have twin 2 year olds who are now figuring out doors. This works well and gives me the comfort of knowing if they try to sneak out of the house. Having 2 littles i swear they take turns distracting me so the other can try to break free. But not with this. Will be buying another one for my back door once I no longer keep my kitchen closed off.

Love this! My daughter is autistic and we have to know if she tries to go outside. I've used many different alarms this is by far my favorite! You can move the speaker to the room you are in and custom the tone you hear.
