What Customers Are Saying

The combination smoke and carbon monoxide detector is generally a reliable product with a convenient 10-year battery life. It provides good value and peace of mind as a combined detector. However, some users have experienced issues with the alarm malfunctioning or going off unexpectedly, and the instructions could be clearer for installation. Overall, the product works well for many customers, but buyers should be aware of the potential reliability concerns and monitor the detectors closely after installation.

Excellent unit

I was using the smoke only version of this device and it lasted over 10 years. It just lost its battery and I have now installed the smoke/C.M. model.

Lowes does not honor their military discount

Product is fine, failure on your part to honor the military discount on this purchase results in my choice to no longer purchase from Lowes.
