Costco First Alert Smoke Detector 10 year battery 2 PACK $29!

Costco First Alert Smoke Detector $29 with a 10 year battery 2 pack. The set i bought from costco 1.5 years ago battery went out so i returned it an replaced them with these. Crossing my fingers that they last longer than 1.5 years… it just means i may have to change it out every year… 🙁
the reviews on amazon have better reviews for this other fire alarm:
