    Perfect for Toddler

    We just moved our toddler into a full size bed and I was so worried about him quietly roaming the house at night while we were sleeping. This little alarm does the trick and alerts us when he’s opened his bedroom door and out of bed.

    Work great so far

    Installed these a few days ago on several windows and doors, 0 issues so far. Had no issues fitting it on any door or window. Sensor detection is nearly instant too!

    Nice for the price 👍

    Just what I was looking for. A simple alert that lets me know when my door is / was opened. It was easy to set up via the app. Is alerts me via my cell phone and works when I'm not home as well.

    Small, Light, Loud, and Convenient!

    The alarm is VERY loud and we can still hear it from every room in our house.
