Easy to set up and install. Our driveway goes to the side of the house and has no lighting. We would have had to have hired an electrician to install lighting so this was an easy answer. Haven't had it long enough to find out how long the batteries last, but it's got to be cheaper in the long run than hiring an electrician. Turned out to be a good decision because this floodlight is EXACTLY what we needed. We put it just at the corner of the house and angled one light to the other side of our back gate, the other to the driveway. Our large greyhound sets it off, but not our mid size dog. Also have it set for just nighttime and that seems to work well. Liked this so much we bought a single for closer to the front of the house.
