The pump is used to well-made, the specified pump capacity keeps largely what it promises. An annoying detail is the fact that the supplied suction cups protrude left and right on the pump housing, one must expect this up to the dimensions. I therefore could not allow it to prime the pump behind my mat filter and must now operate freely suspended / hanging them. While this is not a problem for people who is named as the in the dimensions no more space, is available, this information should be useful. When competition JBL is better resolved because the wells do not protrude above the housing dimensions beyond. Otherwise, the pump top!
