Works well. Easy to install

[This review was collected as part of a promotion.] I recieved this product complimentary as part of my voxbox in exchange for my honest review. I replaced my "smart" fire alarm with this one. The smart one ate through batteries like mad. This alarm seemingly works well, I supposed I won't know until a fire breaks out for sure. But so far ao good.

Very nice!

[This review was collected as part of a promotion.] This is a nice quality smoke detector, the feel of the plastic is a nice premium with smooth finish, it's a but slimmer than my old one so I definitely like that, had no false alarms while cooking bacon either so far so good I will continue to test

Great device

[This review was collected as part of a promotion.] I'm so glad to claim the Rely smoke alarm. The one in the hallway of my home stopped working. The installing the device was simple and it only takes a 9V battery for it to operate. It has a test button to make sure the device sound is loud and working properly. Great device and perform very well.
