Bring light to the balcony

Have since April two yellow and one orange lamp in operation. Delivery on Amazon as always without any problems.
The batteries (size: 1 mignon cell per lamp) were obviously empty and had to be charged the first time.
The lamps were then attached without the black plastic top with Rapp bands outside on the balcony railing.
And there they do their work so far without any problems even when it rains and the lamps are slightly wet. If it is sunny during the day, they light up even until dawn. Even in bad weather and little sun during the day, they light up in the evening for a few hours.
Bin after four months until now extremely pleased with the solar lights.
