4 of 5 great item September 8, 2020
Reviewer: Bob A from WILLOW GROVE, PA United States  
great item and love how it connects to other alarms in the house, including the CO2 alarm.  the only problem i have is that the voice is not 100% clear.  it would be nice to have a customized location - but i understand that.

5 of 5 Well Reccomended August 31, 2020
Reviewer: C.R. Lewis from Denver, CO United States  
This smoke alarm in particular was also recommended by Wirecutter an online Consumer Reports guide. When I found that SmokeAlert not only reccommended as well but had the best price online I bought the four units I needed here. Quick shipping, great price, well recommended - I'm pleased with my purchase! Bought three additional smoke/C02 devices for each floor of my home to pair with these four smoke only alarms.

4 of 5 Programming multiple units August 19, 2020
Reviewer: Ned Drolet from O FALLON, IL United States  
The unit deserves 5 stars BUT the User's Manual  deserve 1 star. At the bottom of page 1 in LARGE  print add " See Top of next page to link units wireless!". Also, certainly the 800 number could be smaller and far more difficult to find said the jester!!! Once the phone number was found and your customer service department reached the day was saved. Your service reps were great!!!
