Kidde is a recognized name in the smoke detector industry. Assuming it's a good product. I ordered a 2 pack at walmart for a reasonable price. Was actually surprised I would find such a convenient package at walmart, and again, for a pretty good price.

Reliable brand

I wanted UL listed reliably designed alarms for my workshop and garage. I installed these on new years so it will be easy to remember to replace the two cheap AA cells each year as a routine. Low battery chirping in those locations will not be too bothersome. The mounting plates are easy to install. In some cases the power goes out (Blown circuit breaker caused by a shorting appliance) before the alarm can sound so AC detectors are of limited value. Lithium batteries last much longer but they also cost much more and I recycle all of my used batteries anyways. I tested these with cigarette smoke and they responded fast. Keep in mind that 10 year old detectors should always be replaced. I have no fire insurance and 5 smoke detectors as well as 4 extinguishers and three fire blankets.
