Easy to Install & Great Performance

We have been buying this brand and model for many years. They almost always last 8 - 10 years on the original lithium ion battery, are very easy to install, and don't produce the false alarms that so many detectors do.

One of the Best Household Smoke Detectors Out There

This basic smoke detector with a long life lithium ion battery is the only one we use in almost every room of our house. It's very affordable. We've been getting 8 - 10 years of life from the lithium ion batteries. The units almost never produce a false alarm beeping for something other than a true fire. They are also small and inconspicuous when installed, blending into the white ceiling. Will continue to purchase as long as First Alert makes them!

Excellent Long Term Performance

I have been buying this model for many years for my home and as gifts for the homes of family members. It is very easy to install, and the long life battery lasts many years 7 - 9 yrs in my experience, reducing the annoyance of changing batteries frequently.

Great value

I found this alarm to be an excellent value. The long-lasting battery easily compensates for the few extra dollars you'll pay over an alarm with a regular 6 month - 1 year battery.

Well Designed & Reliable

We have been installing this model in most rooms of our home for many years--always reliable, easy to install, and usually lasts the full 10 years. Very economical as well compared to comparable models from other brands.

Well Designed & Reliable

Have used this model throughout our home for many years. Reliable and easy to install. Small, unobtrusive design makes it less noticeable compared to competitive models.

Finally! Long life batteries

Tried to get these at local hardware stores & could only get three. So I went on first alert website, found the rest that I needed and ordered them. Prices were better than hardware store, easy to order and I got them right away. Very, very happy with first alert.
