A CO alarm that shows you the reading.

I've had a CO detector for years and never once thought about what it was actually reading. Now I glance at the number every time I walk past. Should have bought one of these ages ago.

Set it up in the kitchen in about two minutes. The display is big enough that I can read it from across the room without my glasses. That alone sold me.

Bought one for the kitchen and ended up ordering two more for the bedrooms. Seeing 003 on the screen instead of just hoping the alarm works is a completely different feeling.

Our furnace is old and it always made me a little nervous. First week with this thing I actually watched the number stay at zero all week. Slept better than I have in months.

Honestly didn't expect much for the price but the screen is genuinely nice. Bright, clear, and it shows the temperature and humidity too which is a nice bonus.

My kids asked what the number meant and now they check it every morning like it's a scoreboard. Anything that gets the family paying attention to this stuff is a win.
