I got the 25 for a 58 gallon mixed tank. its awesome, great flow, i love the random flow option and the wave options. I would certainly buy again and reccomend to others.
I dont think it really compares to the ecotech pumps, its much more comparable to the tunze pumps with a controller, which would cost a ton more.
longevity has yet to be determined on these pumps, but as others have pointed out, jebao is not new to making pumps, they have been making pumps for a very long time for other applications. The only downfall with this pump is customer service in case of a malfuntion, and yes, some pumps WILL have issues, that is the same with ANY product including tunze and ecotechs.
