Review: Does exactly what it's meant to - Bought this for a baby gate that kept getting left open. It works so well, I love the different settings. The adhesive worked fine for me, and it's easy to mount basically anywhere. Well worth the money
Review: Great product - Update: it’s November 14 and the sensor has fallen off the door. I don’t know where it is because my husband probably put it somewhere. I have sent an email to the company to see if I could get a replacement for it and I will let you know what they say. I’m just wanting a sensor and the sticky part. My husband may have taken it off the door I don’t know. My husband has the beginnings of dementia so he never remembers to shut the door to the front of the house. The store alarm is excellent. It has worked every single time. There are so many settings that when he gets used to one sound, I can change it to another sound that gets his attention better. It works even if it’s not exactly lined up because of the door frame. It’s a great product and I’m definitely gonna buy another one for the back door.

### ⭐⭐⭐⭐⭐ Never forget an open door again!
*by B***D on September 28, 2025*

Bought this after a heartbreaking tragedy where we lost two of our Bulldogs to heat last summer. I have it set to alert after the door has been open for 5 minutes. We've used it throughout HOT and humid Alabama spring and summer so far, with zero problems. It functions as stated, loud enough to hear throughout house, doesn't quickly drain batteries, adhesive is still holding strong, and was super easy install/setup. Happy to say that we have not had a tragic repeat of last summer!
