Our Review/Thoughts

First Alert C0910 meets the California state requirement for CO detectors and looks clean

Two screws in the wall and snap it in place

Which would install the alarm with the faceplate completely upside down

Note that if you use the little tabletop stands the text on the unit is upright

This is one of the sleekest CO alarms I have seen

I do plan on purchasing more of these units to replace 5 year alarms I have that are dating out
