I bought this solar fountain about a month ago. The unit arrived in a large box, the base is made by the manufacturer in one pour. When building you just have to install only the base, pour water into the socket cavity, connect the pump to the small rubber tube and put it in the water-filled cavity of the base. Then the pump cable infected by solar part. And already the bubbling fountain in bright sunlight after some time the same lot. Yes, and if the sun should fail to appear, the pump can also be operated with batteries. Something positive I want to mention: Our guests have so far never been recognized that the base is actually made of plastic! All in all a really good solution and my wife has a great joy with our new garden-wall :-) !!!
