Reviewers give the First Alert CO615 carbon monoxide detector good ratings among plug-in models. In one professional evaluation, this CO detector was found to be the most accurate at registering both high and low carbon monoxide levels. Most owners describe this unit as being accurate and easy to use. It can be plugged into any outlet to display both current and peak CO levels in the home and even comes with a battery backup and a power cord for more versatile placement (enabling users to place this detector on a shelf or table). Unlike some other CO detectors, which can be prone to false alarms, this unit can be silenced with a user's TV remote. That said, most owners say this unit isn't prone to many false alarms in the first place. One criticism: It won't display the current CO level unless you press a button, which some users say is annoying. Many people find it more reassuring to constantly see a zero displayed. A few owners also complain about the product's stubborn packaging and its battery door, saying it can be difficult to properly close.

There aren't nearly as many comments from owners here as at Amazon.com. About 10 users give it a very high overall rating, but one owner says he had a hard time getting the battery door to close -- a comment we also found among Amazon.com users.
