Good price. Fast delivery. Consumer reports rated this alarm high. No first-hand experience on how wellit actually works but trust CU’s judgement
Roy Lamberson –
Comes with the slick looking alarm, 2 AA alkaline batteries, mounting screws and instructions. The battery Installation was a pain however with it’s compartment which fought me to open. Took a star for that reason. It complies with with all the standards which is important. But the real test…will it set off to burnt popcorn? Nope! Being it has Dual-Sensors it’s smart enough to know the difference and eliminates false positives.

I already owned one of these units which I had purchased through Amazon. When I found this one at a cheaper price I decided to give it a try. It even came with batteries and a dust cover.

We are very pleased with your product.

We purchased this several weeks ago and I waited to see if there were any problems. So far, it is working faultlessly (thank goodness!)

Easy selection and purchase!..Facts at hand to help with decision…

Shipment was quick. The alarm was just loose in the box, with two batteries rolling around as well. Wasn’t sure if maybe it had been returned and then resold to me as there was no inner packaging/wrapping around the alarm as I thought there might be. But upon inquiry to the company, they indicated many alarms are packaged this way. So, hopefully everything’s good. Product was probably fresher (i.e., closer to the date of manufacture) than what you might typically see in other retail sources. Seems to be working fine, though we haven’t had a fire yet to test the response.

Simple to install and use, just be careful about installing them near bathroom doors. If your bathroom isn’t fully ventilated, the steam let out when you open the door can set off the alarm.
Brian Iwai –
Easy to install and a very loud audible warning signal
Patrick S King –
Great products at a great price. I also appreciate that I’m buying from former colleagues that make sure these products are genuine. I’m a former firefighter and it’s reassuring to me to know that the products to protect my family in my home are just as genuine as the equipment that I wore to protect my own life. Thanks again for these great products and the peace of mind I am getting with them!

Chuck E Williams –
Smoke Alert has integrity. The company stands behind what they sell. I had a slight problem with the unit that I received and after contacting Smoke Alert they took immediate steps to correct the problem. I highly recommend this company.

Jody –
Great product.
Kevin V. –
I had to call the manufacter to get a replacement (on the way) because the detector would go off randomly and finally would not shut off even with silence button. Hopefully the replacement works better.
Dennis Duca –
Easy Installation. Nice Price.

Delivery was ridiculously slow.
Juan Carlos –
I ordered this item, but I received another model that is sealed with a non replaceable lithium battery. I want the unit that uses 2 AA batteries that I can replace when needed. Not happy with smokealert.
James W –
Great delivery ahead of schedule
Dan –
Quality product for a great price. Delivery was very fast. Thanks!

I’ve purchase several detectors with 10 year batteries – both Kidde and First Alert, only to have them fail prematurely, but I have an SA320CN that’s been going strong for 5 years now, so I decided it was time to just go with what works, as it’s still a Consumer Reports favorite. I was not familiar with SmokeAlert, but they had what I wanted at a the best price, and the delivery was as promised. Both units are installed and working just fine. A 5 star experience.
Robert Black –
I almost purchased this smoke detector from Amazon until I saw the same item for $10.00 less and the sam 2 day shipping. I was pleased with everything and will purchase from your company again.
Jean Trester –
Very happy with the First Alert and the excellent fast service from this company. Much cheaper than I could purchase it locally and would buy from this company again.
Ken Kriston –
Upon review of Consumer Reports, I chose this alarm to replace my aging existing ones. Smoke Alert had good prices and delivered on time (fast). These come with batteries included and the screw hole pattern in new base was so cleverly designed that I did not need to drill any new holes!

Fast shipping, had for about 6 weeks. So far no false alarms, hopefully will not have to update review after longer time frame. Like the dual sensor, but it does use AA batteries so have to remember to change periodically
Michael Thomas –
Easy to install, unobtrusive… and loud!
