I love these lights. We used them to accent the area around our patio in our back yard. We followed the directions and made sure we charged the solar batteries for at least 8 hours by setting them out first thing in the morning so they would be fully charged by night. So far the lights have lit up and stayed lit throughout the night and what was even more impressive was that one day was mostly overcast and the lights still charged and stayed lit all night. The appearance with the stainless steel finish looks very nice with our landscaping. The included mountings works great to place them in the ground. We definitely recommend these.
