Bought in 2020. Constantly goes off in 2025. We have 7 of these in our home. So much for 10 year life expectancy. Very disappointed.

I bought this in 2020 and it died. Not the 10 year experience! The manufacturer code says May 25, 2020.

I haven't had smoke detected, however at 4:30am the alarm in one of the devices kept going off, scared the crap out of me! It's dated 2017. No low battery chirp in this devise, it just goes off.

I purchased 3 of these all with the manufacture date of may 2019. All 3 have now went bad. The first of which went bad about 3 years ago. I bought kidde thinking I was buying what was going to protect my house and my children the best, unfortunately that's not been the case. We've had multiple false alarms before the units went completely out.

I just checked all of my alarms and this one was dated 2010 and still flashes every 45 seconds and alarm still sounds when tested. I've never had it randomly go off. Definitely replacing to keep family safe, but I have not had any problems.
