Easy install.

I got this to use in my shop as I work on a lot of cars etc in there and wanted this for some piece of mind especially in the winter. It is easy to install and mount. It seems to be working well so far without issue. It says it should last for ten years, time will tell.

Love the 10-year battery life

The smoke detector works great. Does not pick up light smoke from the stove which our other one did. Easy to install works well.

Works great and super easy to install

I love that this has a 10-year battery built in, has a voice function that goes beyond basic beeps for warnings, and that it is smart enough to distinguish between cooking smoke and a more serious fire. THe design looks great, feels super solid, and was a breeze to install. Overall, I'm totally happy with this detector.
