In my opinion it is crap. It might be just a one off but for me the pump could not maintain it's rated head and would rattle very loudly. At 0 head it was almost inaudible but as soon as I put a highish load on it, the impeller would slam and slap. Gluing the impeller helps.
On the other hand, the Hydor Seltz S30 is the best pump have ever used. Dead quiet, P/Q comparable to a Eheim 1048 at 1/3 of the size, has survived freezing, being dropped and generally abused. If I could find another one I would use two, they are no longer made I think.
So I don't write Hydor off.
