Everything you would expect in a smoke alarm. Emits a loud Sqeak!! When button is pressed. Looks very stylish on my ceiling and in my trailer home. If you don't want to expire in a fiery blaze, these are for you. I also noticed that they are like a suppers ready bell too!

Works great.

I like the small design. It's already proved that it works well without being too sensitive. Easy to install and use. The reset button actually works. Only negative is I need to paint the ceiling because of the old paint from decades ago was hidden by the old detector.

Small but mighty

This smoke detector was super easy to install and I like the appearance of this one way better than the old version we had. Its smaller and just looks better overall.
