The device is made of plastic, is difficult and takes place in the pond easily. To the pump is a plastic housing, which is good from a processing perspective. This enclosure prevents the intake of pebbles.
The manual is a bit thin, and there are little information for the consumer, but it is sufficient to operate the equipment properly.
It git several alternatives, to run the pump. Once a stream pump, here a supplied hose adapter is plugged, set the pump in the pond (in the water) and simply plug it in .. immediately is reliably pumped. In my stream is about 5 m hose with slope. Pumps outstanding.
With the second option, by attaching a nozzle with various adapters, the stream pump are converted into a fountain. Is very simple. Then Again pump in the pond, do and try out the various attachable to change the Spring Brunnes.
Unfortunately, there is no Möglichekit to operate fountains and a stream at the same time. But for the price that is not expected.
All in all I am very satisfied.
