Customer Insights: Rated 4.8/5 from 5 reviews.
We've had this alarm for 4 years now. It's functioned well and is easy to use. Another nice feature is that the batteries are AA and can be changed in the front. We got our money's worth and our lives saved last night we the alarm went off. After realizing it wasn't a false alarm, we were able to locate the cause (our furnace was not venting properly) and keep our family safe. If you're on the fence about buying one - do so!
By law and by common sense, we need to have a CO detector in the home (actually one on each floor by the book). I like that this one has a numeric display and levels of warning. This is our second of this brand and style - they are programmed to give an error code after seven years of operation. There is no repair. I suppose it is because the sensor looses its effectiveness, but be aware that this unit (any unit, actually, if you read the instructions carefully) will only give you seven years of service.
it works and it's nice that it gives u the reading
This is a good value for a battery operated CO detector. I would have rated it 5 stars all around except for one user-friendliness detail. When I first installed the batteries the display showed all 8's. So pressed the reset button and the display went wild. I removed the batteries and tried again and the same thing happened. I finally found that the unit takes 30 seconds after you install the batteries before it starts working. In Kidde's defense there is a spot in the instructions that says the unit runs a self test for 30 seconds after you insert the batteries.
