A great home investment
Pick up these smoke detectors to replace the ones that were in my home. They are easy to install and look great. My only issue is that they come with the batteries already installed which is a good thing but of the six smoke detectors, I had to replace five of them.It’s a quality product, but I wish they would have dropped the price and sold them without the batteries cause you still might have to replace anyway.

Great package of Smoke Detectors to keep you safe
Easy install to replace my 10 year old Detectors. Nothing fancy but seem to work fine using the test button. Fortunately, haven't given them a test a real fire or terrible cooking. The electrical connector matched my old model saving installation time so look at your existing connector before disassembling the electical connector. This is one item I hope never gets used, replace all yours if they are 10 years old or more.

Great wired smoke detectors.
Had to replase old smoke detectors in my house. Checked with big box stores, settled with Amazon. Excellent price for a pack of 3. Priced less than 1 in the big box stores. Name brand, easy installation. Highly recommended.

Almost perfect drop-in replacement.
Replaced the three alarms in my house with these, came with everything needed to install them in the place of the old ones. I only dropped a start because for some reason one of the batteries went dead super early, but other than that they are perfectly functional.

Smoke alarm
Easy to install and life cycle 10+ years. Well worth the money. REMEMBER, Smoke Alarms should be changed every 7 to 10 years.
