    Great Company

    Bought 2 of them at the price of 1. They work as promise. Like the fact that it has false alarm turn off button and the battery backup for when the electricity is off. Also installation was a simple. They don’t have mounting screws in package, not a big deal just used old ones. Would be a problem on new install.

    Great product

    Both smoke and carbon monoxide alarm. All alarms in house are tied together to go off when one alarm goes off

    Good product

    This smoke alarm came as advertised. I like the lithium 10 year battery alarms. Just make sure you pull the plastic battery tab in the correct direction. The housing is sealed so if you mess it up the whole thing is worthless.

    Perfect replacement for 6 to 7 year old identical units.

    Perfect replacement for the same identical units that were 6 to 7 years old which no longer worked due to a "malfunction" trouble signal.
