Universal Security Instruments (3-Pack) 10-Year Battery Powered Mini Smoke and F

Got a 3-pack of these Universal Security Instruments smoke alarms. They're the compact "Sensing Plus" models so they don't look like those giant eyesores on your ceiling. Best part is the 10-year battery life, so you dont have to deal with those annoying low battery chirps in the middle of the night for a long time. Super easy to install and keeps the house safe. Box is a bit worn but the units are brand new.
