Got this around 1pm , noted it was fully charged, placed in the garden, ……..and sat out around the patio about 10pm. It was SO impressive! At dark time the shape of the “flower burst shape” appears like big 2-3” color changing star-spheres. The “crystallized” clear flowersspheres appearance in day time is very contemporary. 
Great out if the box! Easy set up! The papers suggest changing the battery once a year.
