Overall, the smoke detectors that we gave the highest rankings to were from Kidde. However, there were many units from that manufacturer that did not fare as well. The same is true for other brands including First Alert. We recommend looking closely at the specifications for the smoke alarms you are considering. Make sure they have the features you need, and read some of the comments from buyers to see if there are any recurring issues.
