  • Safety 1st

    Hi, I purchased 2 packs of these First Alert designer style combo protectors. I love the slim modern style and programmable feature but I bought mostly for the 10 year warranty. Install was easy but directions poor and limited. I had to call First Alert customer service for programming help. These replaced my current combo detectors that had battery failures 5-15 times a year for 5 Kiddie combo detectors. Plan to purchase another 2 pack. Happy to have tech support to assist. HSN assisted also.

  • Great Saftey

    Great product that makes me feel safe when I sleep. Very loud volume. Test button gives you exactly what it will say if it every needs to go off. Plus that will last for 10 years that is incredible. A must buy.
