I bought these to light the pathway to my backyard apartment. They were super easy to install - I love that all I had to do was screw the light onto the post and stick them into the ground. Just make sure to turn the switch on after they collect sunlight for a few days. When they go on at night, the lights are certainly bright enough to help me see. However I am only giving it 4 stars because the lights don't stay lit for me all night - there have been times that only some of them were lit up or none at all.   

Pros: Easy to assemble, durable, looks great
Cons: Does not stay lit long enough
