Very Satisfied!

Not much you can say about a smoke detector. I hope I never know how well it works! This is my second one of this model, and I've been very pleased with both.

Nice choice for young adults

The Nuisance Resistance Feature is a nice feature. I am hoping it increases compliance with use. Practical gift for young adults living on their own

First Alert with Smart Sensing Technology

I replaced a older alarm with this one because of the good reviews and the known technology. Very easy to install using the screws that were used for old alarm.

Recently ordered from first alert. After reading reviews on smoke detectors I selected these. The website was easy to navigate, the price was the best I could find, shipping was free and the product arrived quickly. What more could you ask for?

Very accurate

We switched out our old brand for First Alert and it made a noticeable difference. Alarm alerts at the first sign of smoke. So much peace of mind now!

Review of Order

I've only just received them. Got exactly what I expected at a price that beat ordering from other stores. Time will tell for how they last!

Simple Solution

Easy to install.I used the battery powered detectors and their performance is as good as hard wire if you remain diligent about maintaining batteries.In an older home the SA320CN is a great alternative to the hard wire model and installs in minutes.Don't take chances with your property or family and you'll sleep better once you've put these up.Simple to follow directions.I was done in no time.

Solid Smoke Alarm that detects both kinds of fire issues

Finding a battery operated smoke alarm that detects smoke both via ionization and photoelectric is not easy. This detector does so, and with an advertised smart sensing, and nuisance resistance to minimize falsing alarms. The smoke detector came with all accessories needed to mount the detector, and installation was straightforward. I prefer a brand name like First Alert over some new foreign overseas Chinese companys products for their known track record for piece of mind. Saving a few bucks, or adding some new gizmo feature is no where near as important as having confidence in the quality and accuracy of something as life, and death important as a smoke detector/alarm.

The product packaging was appropriate, with the product presented thoughtfully and protected fully, but not overpackaged. I appreciated the fact that the footprint was the same as the First Alert smoke alarm it replaced, so we used the same holes in the ceiling and covered the same slight discoloration that occurred on the ceiling in the 10 years since the last one was installed.

Researched smoke detectors and found this was highly recommended. Bought six and have been very happy with my purchase.
