## Product: Kidde Nighthawk Carbon Monoxide Alarm
**Brand:** ‎Kidde

The Kidde KN-COB-B-LP Nighthawk Carbon Monoxide Alarm is pretty straightforward and reliable. It's battery-operated and kicks out a really loud alarm sound when it picks up unsafe carbon monoxide levels. Our research suggests it's hard to miss, even if you’re asleep or in another room. They don't specify the exact decibel level, though.

It doesn't have a digital display, which might be a downside for some, but it makes up for it with its simplicity. There’s a green LED that lets you know it’s working fine and a red one that warns you about dangerous CO levels. It’s easy to get the status just by taking a quick look.

The alarm runs on three AA batteries, which is great if your power goes out often since it stays active no matter what. Plenty of reviews mention this is handy for areas with frequent power outages or if you don’t have AC power.

If seeing the current CO levels at all times is important to you, you might want to check out another model, like the [Kidde KN-COPP-3](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fdp%2FB00002N86A%3Ftag%3Dssw.ans.tx-1-20), which has a digital display. 

But if you just want reliable CO detection without the extra features, this model does the job well.
