The high quality device will protect your home from toxic carbon monoxide. Building codes encourage the use of these devices so I bought one! This is a very useful product and free shipping made me a believer. Thank you Overstock!
The motion sensor works well on this unit. The "alarm" is loud enough to alert you when motion is detected but not so loud that it wakes up the neighbors.
I installed 8 of the light sensors around my home. I am a newly owned homeowner. Where I live there are no street lights. These lights are amazing & have made me feel much more secure; to brighten up darkened areas; the motion sensor gives off a bright light when detects motion within 10 ft away. Set of 2 for under $$, amazing!
