These lights were an unfortunate gift for my mother: At first she was very enthusiastic, because the nice swimming ball brought a beautiful light in your garden pond, the gently by the wind from one end moved to another. The first unpleasant surprise was followed by about 2 months later, when the first light did not want to light up :( Shortly thereafter, did not want to light up even the second light and so you fished the - not so cheap - balls from the pond. Spectacular: Both "Floating Lights" were leaking and apparently not suited to really swim. The water is passed through the cable hole in the ball and has selbige rendered useless by rapid rusting.
