For a price of about 50, - Euro per lamp I had eingentlich expect a high quality product. But apparently, the S-Force 3378 Luce LED Solar Garden balls, in this case differ in execution 30 cm and white, not by many cheap products. First, it must be held that the charging on the seated in the solar light the balls hardly brings to light during the winter months. In summer, weather permitting charging is sufficient to produce a slightly bluish glow for a few hours. Now, after one year use the plastic balls have probably get through the sunlight on top of yellow bodies and have thus become quite unsightly.
All in all: The lights are not worth their money.
