Ordered 8 pieces, one did not go out in the light,
With the help of a screwdriver and a glass of beer I looked inside, it turned out that the wiring was soldered from the solar panel
After the second glass, he warmed up the soldering iron and put it in place, assembled the structure)
After the third glass hung on the wall and that's it))
In general, they do not shine very brightly, but enough not to stumble on the cat in the dark)
