I bought this pump to a small fountain in the pond in my garden, but I'm rather disappointed. The image of the presentation and taken so that it deceives the true size of the object. Since a week I m ^ sunlight water does not rise above 40 cm. height. You really need full sun for it to work, and more are supplied tips are very fragile. I think I'm going to put it in a bowl and in the summer if I want to see it work.
