Replacement for my previous Kidde detectors that had reached end-of-life after seven years. Direct replacement using the same connector and mounting plate. I installed both photoelectric and ionization types for better protection. Only rated this with four stars because there are newer, better, detectors now but they were out of stock for an unknown amount of time. I bought these because I needed to have something installed. These aren't bad, just not the best available now.

This hard-wired smoke and CO2 alarm provides a level of safety and assurance and does so without any high maintenance - just a change of its 9-volt battery when called for. Essential for any household.

Easily installed. Front battery door makes battery changes easy, no need to take down. Installed 3 units total. No issues at all. If one goes off, they all do.
Verified purchase: Yes | Condition: New
I purchased 8 alarms and 5 looked new, but 3 had been taped shut and the plastic tab removed which activated the 9 volt battery. Also one of the alarms is defective, when I connect it to the system it sets off all the other alarms. The price was excellant, too bad one was defective.

Excellent product. It came in perfect condition and it is working fine so far.
