Great product June 15, 2017
Reviewer: Anonymous Person from Los Altos, CA United States  
I have several smoke detectors. But they are supposed replaced every 10 years. Most of mine are 20 years old so it was time. This replaced an ionization unit and works perfectly. Also AA batteries are much easier to change. Only issue is that I wish they would have shipped the (much more expensive) Lithium AA batteries that last longer. But I can understand how they wouldn't put $10 batteries in a $30 smoke detector. I will put them in when the current ones die.
