Title: First Alert 120-volt Wire-in w/ Battery Backip Smoke Alarm
Review: I orderd six of the smoke alarms. The items that arrived had no battery backup. I contacted the seller and they apologized and said they did not have any of the item they advertised. They paid for return shipping and issued a full refund. I purchased the correct items elsewhere and they are a nightmare. As in most other reviews of the same item they let out 1 long beep at all hours of the day and night for no reason. This causes doubt in the proper workings of the product and therefore useless.
