Solar Mason Jar Fairy Firefly String Lights Regular Mouth Lid Cool White 20 LED's

Had similar lights that lasted over a year, outside in all seasons. Got this as a replacement, as it was one of the few available singly, not in a set. Took a few days charging before it worked; then it would typically only light up for an hour or less. Color is blueish, which I liked less than the the warm yellow cast of the other ones. And now it has failed completely.

I bought two of these lights. Neither one worked. when I opened the battery to see if it was put in correctly, I found that the batteries were leaking. Asked for a refund and that was promised, but as of today I still haven't received one. That was over two weeks ago. These lights are junk.
