Bests & Worsts Reviews from Amazon

So far, so good. Of course it’s hard to rate a smoke detector unless you have a fire. This unit replaced a First Alert unit that was only three years old that often sounded a false alarm, or was too sensitive to standard cooking fume. This unit was very easy to mount to the ceiling, probably less than three minutes once I got the stepladder and drill to the desired location. This unit is a little smaller than the First Alert and doesn’t have the same footprint on the ceiling, so if the ceiling had been painted a different color you might want to use a little touch up paint around the base. Hope the battery lasts the suggested 10 years. One thought about the smaller size of this unit. As mentioned, I had frequent false alarms with my previous First Alert where I could barely reach the unit to silence it while on my tippy toes. This unit, being smaller, I might not be able to reach it without a stool / chair to stand on😁
