Cappy: Excellent product, but still took 2.5 weeks despite Prime delivery. (Most likely because they were waiting for NEW inventory) In fact these detectors were only 1 month old, which means they were brand new so worth the wait. However they were re-boxed in plain brown cardboard. Most products for new construction come this way. Anyhow I’m very happy as they operate perfectly! Took one star off because I was told by the manufacturer before I purchased them that the use of AA Lithium batteries were ok, when in fact the instructions say to not use AA Lithium batteries.

jenat: When I first received this alarm, the battery door became stuck between open and closed and I couldn't fix it. Went to the Kidde website and saw that several others had the same problem. After trying the recommended fixes, I called Kidde and the rep agreed to send a replacement since I had tried everything. The new unit arrived and is now functioning properly. It's a unique alarm since the voice tells you what the alarm is and you don't have to count beeps.
