Query: Simplicity is wonderful

I hope they continue to make these. I have some other smoke alarms with batteries that GO OFF in the middle of the night. Last night at 4 AM my bedroom new talking smoke alarm started to say “Low Battery” every five minutes. It is installed high up on my bedroom wall. I had to go to my garage and get a ladder to remove it in the middle of the night. Today I’m going to install this simple 120 volt smoke alarm so this 4 AM removal of a new expensive but defective talking alarm will never happen again.Simplicity is wonderful !
