Wow, so easy to use!
Take it out of the box and mount it wherever you'd like with 4 screws. Then there is a simple on/off switch. The motion detection seems to work well and it does put out a powerful light which I think is impressive for it running only on solar power.
It does look a bit like a security camera, so that is a nice safety feature too.
If you are looking for a simple motion light, I would absolutely look at this Bell + Howell spotlight. Works well and great price!
