Almost perfect (9/6/2017)
First I bought just one and gave it a few months to see if it would hold up. I liked that one so much I bought another, and then a third one. I use them in "motion sensor" mode and I like everything about them except I wish they'd stay on longer than 10 seconds because I can't make it from my front door to the newspaper box and back with out them turning off and then back on. Other than that, I'm very happy with them and they seem to be holding up well so far.
