Review on 🔌 Kidde Nighthawk Carbon Monoxide Detector - AC Plug-In with Battery Backup and Digital Display by Fernando Ramani

As an installer I can attest that Kidde saves me time because they get all the little things right with mounting hardware etc. The PPM reading is important to me because if an alarm ever works, that's the first thing to do. What I'm going to do is read the display. I will then open a door or window and see if the display changes accordingly. And if not, then I exchange the device as defective and don't let the alarm ruin my life. After shutting off the gas, I'm hoping to move the device to the source and find the leak. So if I have a display, I have options.
