While these alarms are pricier than some of the others I elected to purchase them because the lithium battery would mean no changing of batteries, and its not easy to get to some of my detectors and I can get unbalanced fast on a ladder! The Customer Service email contact was EXTREMELY helpful with both tech information and the right alarm to get for the hardwire I already have. I shared with others in my neighborhood this information on our blog!

easy to install, no false alarms so far
This smoke alarm was easy to install, uses the same kind of connector as Kidde alarm it was replacing. No false alarms so far.

Arrived promptly and was easy to install. Should do me for 10 years but it was nice that you did what you said you would do.

Great fit & function
Exactly what i needed. Slim design, great technology, and ease of installation. However, the plastic battery protector pull tab on 1 out of the 5 tore off incorrectly. It's unretreivably stuck inside which caused it to not activate. In process of getting a replacement.

Hi, had to replace my detectors since they were starting to go off when I cooked. They were 10 years old. I ordered 2 iono detectors 3 photo detectors and 1 carbon monoxide one all 10 year sealed and wired ones. They all installed and worked good and solved my cooking problem. Also the customer service was very responsive and the items were shipped quickly A+. Kevin
