I emailed customer service to find out the product manufacture date for Kidde smoke alarms prior to placing the order. I received an email back giving the manufacture date, which was very recent (within 2 months of the inquiry). I ordered the products based on the information given to me, and when they arrived, they had the same manufacture date as I had been told by customer service. The price including shipping was much less for the exact same product online elsewhere. We received the products quickly and installed them and they work great.
