[This review was collected as part of a promotion.] We needed something easy and non-techy to install on doors and windows to ensure our 94-year old mother wouldn't wander outside without us knowing. In the past she's opened the sliding back door and walked down the street. She easily gets lost and will get very upset... it's horrible. We have great neighbors who are aware and very helpful but these little door window alarms are fantastic. They were super easy to attach to the sliding door, her bedroom window and our side door! They even came with the batteries and little mounting strips. I recommend you plan where you want to place them cause they stick really well!! I went to move it after a day (since mom kept poking at it) and it was securely mounted on the window. The settings (we use the little bell) are under the little removable plate, so mom wasn't able to turn it off or fiddle with the settings. Definitely great for peace of mind when I am in the other room doing dishes or checking on something in the oven. We don't use the alarm setting but man is it loud. I set it up the first night just to test. My husband practically fell over himself when he opened the sliding door to let the dog out. Really happy with this purchase.

[This review was collected as part of a promotion.] Installation was easy. The sound was not the best. My battery didn’t last long had to replace twice after two week of use. I would not recommend to purchase maybe just for simple alert Use.

[This review was collected as part of a promotion.] The sticker for the wall was easy to apply but when I tried to reposition it, it did end up ripping some of the paint off. It's very loud so you will hear it from all parts of the House. Overall it's pretty good for the price.

[This review was collected as part of a promotion.] I couldn’t review this product because the batteries were dead. I was very disappointed because now I have to go out and buy new batteries and I was hoping to try this product out right away.
