I would give these no stars if I could.  These lights look NOTHING like the picture.  Even after charging them (in bright sunlight) for two full days, they are barely visible on the trees.  I am beyond disappointed.  I am returning these.  It is December 7th and I'm having to take down lights (8 sets), re-box them, ship them and then put up other lights - all before Christmas.  As you can imagine, I am very disappointed and unhappy with this product.
