From opening the box to installation was taking just one minute. The Smoke alarm comes with a 9 Volt battery, ready to work. The size of this unit is little, and do the same work like a big ugly smoke alarm. I never have fires in my place, and I install this alarm because of the regulations, because was cheap, because was easy to install, and now looks great on the ceiling.

EASY PEASY to install. Do not spend money for expert installation. A person who is not handy but can follow clear directions can install this themselves. (Could be installed with a screwdriver and a thumbtack -- no special tools required.) Batteries included -- both were fully charged and ready to go. Would recommend and would buy again.
