Can't speak to quality yet, but it's a great design. The 2 pack of CO alarms save big bucks over name brands, which I always thought were egregious, but it looks like siterwell has established its reputation. Runs on 2x preinstalled Energizer AA batteries with a pull tab to allow connection to be made after you open it. Supposedly each set will last for three years, so you'd change it 3x to get 10 years, with two batteries only having been used for 1 year, so you're preparing to put 6 MORE AA batteries in there. I have NOT yet experimented with NiMH's, but I doubt they'd work, and it's a safety thing, so more alkaline batteries for the landfill unfortunately I guess... of course I have no idea what's in the big Kidde plug ins with 10 year backup battery, but I've had a couple fail recently, so, trying something else.Read full review
