I purchased 10 solar lights in Aug and Sept of 2016 costing approximately $11. Piece. In June, I saw that one wasnt working. My husband took it down and found that water had corroded the inside. I tried to call Open sky and found you can only contact them through e-mail. That was a red flag. When I did contact them, I was told I only had 14 days to return it. How would I know in 14 days that a solar light is defective. Last summer we were in a drought here in SW Florida, and it didnt start to rain hard until this May which is when the defective seal became apparent. I would never deal with this company again; obviously, they are not concerned with retaining customers. They just want to sell as much of their shoddy merchandise as they can. Id give then no stars if I could. I now see that I could have purchased these same light for considerable less from a company that sells on ebay.
