Unit ceases to function after seven year

Pros
Lasted For Seven Years
Cons

Comment:
Unit ceases to function after seven year by design. The packaging states that after seven years the device will automatically alert that it is time to replace. What it actually does is deliver an error code after seven years and, per their web page, does not detect the presence of carbon monoxide when in this mode. Apparently it cannot be reset and you have no protection until you replace the unit.
How long have you owned it:
More than six months

Comment:
Used this Kidde Nighthawk for just over 7 years before it Err erred out today. Kidde offers a 5 year warranty, which I think is good and this product exceeded that. Kidde also recommends you replace your CO products every 7 years. Nothing lasts forever, so this makes sense to me especially since this is a product that protects you and your family's life. Thankfully we've never had ours tell us to Get Out. I'm going to buy this same exact model today.

Yes, I would recommend this to a friend.

Comment:
The backup battery is actually mandatory. Once it starts to get low, there's no way to stop the loud chirping other than to disable the unit entirely. The battery does not come out quickly. If you don't have easy access to both hearing protection and a fresh battery when it starts chirping, you're out of luck. We had to unplug it and let it chirp the night away in the car, leaving us without any form of CO detection. Power outages are extremely rare here, so the backup battery actually increases the odds that we will be left without protection. <br /><br />The peak level reset does not work. The number is always the same. This makes me question the reliability of the unit overall.<br /><br />We would gladly pay more for a reliable and accurate unit that we could just plug in without all the battery fuss. Why does no one make those, apparently?
