Great Detector — Easy to Use and Gives Peace of Mind
I’m really happy with this smoke and carbon monoxide detector. It was super easy to install and the LCD display is a huge plus because it clearly shows the CO levels, so you always know what’s going on. The alarm is loud enough to hear from another room, and I like that it has simple indicator lights for power, alarm, and faults.The test button works well, and the unit feels sturdy and reliable. It runs on batteries, so no complicated wiring. I feel much safer having this in my home—definitely worth the purchase!

Peace of mind
Easy to hang and the face is big and bright making it easy to read, has a test button so I know it’s working. Detects smoke and carbon monoxide so no need for two detectors. Also looks good on the wall it’s the perfect size.

Visual appealing with duel functions
Great product, it had the batteries included easy to install and will be easy to change batteries. It is duel so it checks for carbon monoxide too. My alarms were older and did not do that thus why I’m changing them out.

Loud, easy to install, and use!
The smoke/carbon monoxide detector works great. It was easy to install, and comes with batteries ready to use, and is loud enough to hear easily for deep sleepers like us. I like the LED screen which makes it easy to see. It has a test button to make sure it is working. I feel our home is a little more safe with a new smoke detector, and I was happy to make sure the carbon monoxide levels are normal. I can sleep easy knowing we have taken safety precautions. I will be purchasing more as soon as possible for other areas of our home.
