Review: Reliable Kidde Detectors & Easy Install - Excellent Kidde smoke & CO2 detector. Easy to install and I also purchased the Kidde Quick Connect Adapter made for these detectors as the plug had changed from my old Kidde detectors. I could have done the plug wiring again as I did for the previous detectors, but the adapter was simple, easy and not very expensive. I do wish detector plugs were standardized across the industry, much like USB hook ups have for the electronics/smart phone industry. The detectors I purchased are hard wired via plug and also have 2AA batteries as backup. There are models with a "10-year" Lithium battery permanently installed as backup, but I've never gotten 10 years out of older models so decided to just change the batteries every 6 months when I test them.
Review: Perfect replacement - They fit perfectly over the old ones. Slid right into place. Have no complaints.
