At $195.00 ea. they better be great! Better run forever with proper care as well. I really would like to put a pair of them in my future tank if I ever get to build it.
I've had a MP10 since they came out and no reliability issues yet. Anyone who hasn't heard GREAT things about Vortechs hasn't talked to many people who own them. They are not a pump; they are a force of god!
