First Alert Smoke Alarm w Voice May 3, 2017
Reviewer: Carol from Richmond, TX United States  
Important to follow the instructions when setting these up. Installed 5. They are loud when you are setting them up so you may want to remove small children and pets from area. Feel safe with these now.

Great Experience March 25, 2017
Reviewer: Daniel MacDonald from New Boston, NH United States  
For all of the purchases I would not think of going to any other outlet for these items. SmokeAlert's employees provide the best advice and expert designs to ensure I get what I need without overspending. Can't find this kind of customer service anywhere,..
