Looks great, after 2 days but was out of breath

As the fairy lights came, I was thrilled. She looks great and is really beautiful light.
For the tree, it is not really suitable because it is much too short. But as decoration on the windowsill she looks good.
I connected it and loaded the required 6-8 hours.
The next 2 days we had a really nice evening bright light.
The chain even still lit up around 23 clock.
On the third day, however, remained dark in the evening. Despite several attempts at revival, they did not want to light up easily.
At most a short, faint glow could be seen before again there was darkness.
Too Bad.
I'll try again to send. Maybe I will not get compensation.
