FIRST ALERTSA303CN3 Battery Powered Ionization Smoke Alarm with Test/Silence Button, White

Received in excellent condition.

Works well, pleased with my purchase.

This smoke sensor was so easy to setup I laughed. If you can use the same screw anchors as your old sensor, this install will take about five minutes. Easy to read instructions, and best of all, no need to remember to change your battery every six to twelve months because these products have a “10 year” battery life! And the cost is relatively inexpensive. Best of all, the sensor will pay for itself the first two years you use it because of not having to pay for all those darn batteries!I highly recommend this product because of ease of installation and setup, cost savings and for keeping you from having to climb a ladder every 6 months. These are great for seniors too!

Yes I’m sure the alarm is a good product but I never received it after 1 month , DHL not so good 👎

I purchased 2 for $15 and one stopped working after 3 years. I changed the battery, but light still red. Called mfg and was told the unit is defective, I have another as a backup, so it doesn’t matter to me. Woke me up at 3am, but I guess that’s a good thing.

Hopefully it lives up to the long battery life listed but will be great not having to worry about the batteries running out so frequently.Installation was a breeze as you don't need to even plug them in, being fully battery operated. You can just put them anywhere with a few simple screws (included with drywall anchors).The ones I installed chirped just fine when holding the test button. There is a small red LED that flashes every several seconds though. I suppose this is to let you know it's doing its thing. It's actually a little brighter than expected.Hopefully It never gets used but great having a well known company behind the units. They are shipped in plain builders boxes for those that reviewed them being fakes. The units themselves are exactly what was expected and pictured, from First Alert. Maybe it would be helpful on the page to have this better pointed out to not catch people off guard.Overall great product for great price. Some of those fancy ones are nice but just so expensive, and then issues with the app's over the years are no fun. Some things are just better simple.

I bought two of these to replace older smoke detectors in my home. They were easy to install and with the 10 year battery life, they will be no trouble for a long time to come. No worrying about when to change batteries or that annoying chirp that ALWAYS starts at 2:40am! I do like that I recognize the brand name. Too many products on Amazon are chinese names that I've never heard of before. I can't comment on how well these work as I haven't had a fire, thank goodness! But, I am confident that we are better protected than before...
