Title: Works?
Review: My wife has a bad habit of leaving the back door open. In Florida, lets the AC/cooling out, and bugs in. I work, and she spends my money. I would rather spend it on something different. After many debates over this, I purchased this product to install on back door. After I showed it to her and talked about the "extremely noisy alarm", I found I did not even have to install it. Is it functional? I have no idea, but it solved my problem, with minimal installation. I gave it 5 stars, since it does the job, with no installation required.
Is this product review negative?
