Excellent unit with great features.
After extensive research I decided to purchase this unit and I'm glad I did. I wanted the following features in my CO Detector, and this unit meets those requirements. It must be AC powered with battery backup, have a digital display, use AA batteries, not the expensive 9 volt, have an AC power cord so the unit can be located away from the AC plug-in if necessary, have a long warranty (7 years) from an established company, and be competitively priced. The only possible negative feature I can see is that the front battery cover is hinged on the bottom. The battery cover retaining latch seems to be rather flimsy, and if it were to break, the battery cover would flip open. The cover hinge should have been placed on the top of the unit or a better latch system used. Hopefully with careful use the latch will not break. It should be noted that the unit has a built in “in-use” timer that will alert the user and disable the unit after 7 years of operation.

Useful device
The CO detector is a little larger than I expected, but the design is unobtrusive, so I hardly even notice it. It was very easy to set up and is easy to operate and read. The one problem I encountered was with the outlet I wanted to use. This outlet had the prong holes one above the other, and at first I was concerned that the detector would look funny sideways on the wall. Fortunately, the folks at First Alert had anticipated this Issue, and the power adapter can be flipped 90 degrees so the detector will display horizontally. So far, I'm very pleased with this unit. I only just got this, so I can't comment on its longevity. However, I did check and the date on the package puts the unit at only 4 months old. This is good news as other reviewers have reported getting units that were manufactured 6 years prior to sale leaving only 1 year of life on their units. Fortunately, that was not a problem with my purchase.
