Amazing fire and smoke alarm!

This smoke and fire alarm is amazing! I love that the battery lasts 10 years! It was so easy to install and is small and compact, you hardly notice it. I also like the feature to silence it if it goes off unintentionally. I also like that it will notify you when it is ready to be replaced. I mostly love that after installing, I won't need to think about it for 10 years!!

Easy to install- no batteries to replace

Been wanting to swap out my standard 9volt smoke alarms and it couldn't have been easier. These came in a 2-pack, and the 10-year lithium battery means I won't worry about it for a very long time! One thing I adjusted was that I used my own mounting hardware instead of what came in the box, although I'm sure it would have been sufficient.

Easy install

I needed to replace my smoke detectors and this was the perfect product for the job. It was really easy to install and didn't take long at all. It works well and gives me peace of mind that I will be alerted during a fire. I love that the batteries last 10 years so I don't have to worry about a lapse in protection.
