Life saver
We just moved to a busy road and with my toddlers this was a must. It's super easy to install and loud enough without being too loud. The design makes it super easy to switch the settings. I only wish there was a way to change settings from your phone. The adhesive is good quality but could be better as the slimmer part of the sensor has fallen off of one door a few times but I think that may depend on the style of your door frame too.

I recommend it, easy to use.
I purchased this 4-pack of door and window alarms and, so far, I'm very satisfied with the product. The packaging is clear and straightforward, and includes everything needed for installation: alarms, mounting adhesives (3M), and the components in individual bags. It's an excellent option if you're looking for a basic, easy-to-install, and effective security system. I especially recommend it to those who live in apartments or small homes and are looking for a quick solution to protect vulnerable access points.

Great for autistic children.
I put these on every door for my child with autism. The alarm is nice and loud. It sticks very well to the door and wall. However, be mindful that the tape that sticks it to the wall/door normally does rip off paint. For that reason, I normally buy command strips for it.
