Bought in July 2012, 2 lamps. A solar panel was already defective upon delivery, but was replaced at no charge. After 1.5 years a solar module does not work anymore because of Corrosion. In both lamps Moisture has accumulated, so it's only a matter time when these bye the 2nd solar module. Here missing clearly the necessary seals. Phoned Skapetze: The following statements are made :: Had we not have a problem, or there is no guarantee for battery and solar panel. The spare parts (solar module) will cost about 40 euros. Outrageous, I paid back then for 2 solar lights 39.
