Easy installation. We have had cloudy weather since I installed this solar layers. Even with cloud cover I had light for over 5 hours at night. It covered the time period needed until we hit home. Gives enough light to brighten up the entrance of my drive way. 
Loved the option of 3 different ways to mount this layers. I had an old post that was smaller the the attachment but found a pipe adapter that fixed the size difference. 
It is very pretty when lite.
