So surprised to order something from a factory store and pay less than found on other sites on the internet. It was quickly shipped and received.

Reviewer: M Mermelstein
I replaced a First Alert alarm like the one I had. For some reason it just kept chirping and new batteries made no difference. After checking several local retail stores and not finding an alarm like the one I had, I found the exact model online at First Alert. The order process was fairly easy and the alarm actually arrived ahead of the anticipated delivery time. The alarm was exactly like the one I had. I am totally non technical and would not attempt the installation so I had a friend install it and apparently the process was fairly easy and the alarm immediately worked when installed. Am very pleased to have been able to replaced an alarm with the exact model I already had. Very pleased with the entire process from ordering to receipt to installation and am quite pleased with the alarm.

I bought a 9120B smoke alarm to replace an existing defective one. I just changed the smoke alarm not the base. It is very easy to replace. The new alarm is working fine and there is no issue. However, the product is delivered later than the promised date.

These were the smoke alarms that were installed in our home when I bought it in 2010. They have worked well since we moved in, and since the house was built in 2007, I figured it was time to replace them. That's why I ordered the same model that we had already.
