The lights are all functioning.  With plenty of southern daylight, the lights last throughout the night.  You must be careful in installing the lights.  Insure the hole is larger than the diameter of each light and when installed, pack the soil around.  I have the lights surrounding the front steps leading to the house.  Placed near a newly installed retaining wall, the lights cast a very nice reflection off of the stones.   

Pros: For the price, a good value.  I especially like the bronze color.
Cons: Not sure of the durability of these Lights, but only time will tell.
