    The initial packaging was sealed with a lot of dirt and debris inside. I returned it and was sent a new one which was fine. How strange.

    This item is damaged. The front cover will not close with the back up batteries installed. It keeps popping open. I have been trying to find out how to return it, but the hold time is TWO HOURS and the CHAT feature is disabled. This is not the quality and customer service I expect from Best Buy.

    This product was easy to set up! I had a gas leak in my house which caused me to buy two of these for peace of mind. No issues with this alarm.
