Best alarms - 05/12/2018
Reviewer: Jen S.
I did a lot of investigation before I ordered new alarms. These had all of the options I wanted and they are so much cheaper than the other name brands. I installed them very easily myself and they have been great. Never had any false alarms. There are no annoying lights. I really like that they have different ones specifically for the hallway, bedrooms, and the kitchen. The previous brand I had in the kitchen went off every time I opened the oven. These don't since it senses the difference between steam and real smoke. These have USST technology which is much better than the other brands. I highly recommend this brand.
