I love these mason jar solar lights. They add a whimsical feeling to my front porch. They remind me of fireflies when I was a child in a jar, just different colors. The came with a jar and the hanger. The solar panel charges during the day and they were on almost all night long. Everyone has made wonderful comments and keep asking where I got them from. I also love the fact that they came with the rechargeable battery already installed and it has a door to replace the battery when needed. No dissecting it to get to the battery. If you want the to rum during the day you can cover up the solar panel with something and they will come on. Theres also an on and off switch if you want to turn them off. #RankBoosterReview #Kavin HO #ERUW
