This makes a loud alarm once plugged in and loses power. I like that there are different sound levels. My negative 2 star is because it takes up both outlets. You cannot use the other outlet no matter how you plug it in.
Let me explain. If you use the bottom outlet to plug this in, the top outlet is blocked obviously. But if you use the TOP outlet, you would expect to be able to use the bottom outlet. But no, this device extends into the bottom outlet by a few inches. This makes it not a good solution for the outlets.
I had to buy an extension cord and plug this into the extension cord next to my fridge.
