I was very much in need of this because in my neighborhood, it is lacking enough street lights and we've had some recent crime in the area and I want to make sure I can keep a better eye on my yard. 
I love that this has motion detection. I like that it doesn't take batteries and works by solar. It's an easy setup as well. I chose to stake it rather than mount it to anything. 
The lights are bright and definitely making me feel better about my yard. I can and will recommend this to friends.
