Well, I joined the club today. My first impression is very well made pump, small footprint in tank. Looks so much better without other pumps in there. Flow it generates is tremendous, very easy to understand controller. Unfortunately it is not silent, it is quiet when on constant flow mode under 40%, but higher flow and the noise becomes very noticeable. When pulsing, it is pretty annoying when ramping up and down. Almost like vortech pumps. Keep in mind that my system is very quiet, almost silent. Can't hear any of my equipment when couple of feet away, so to me noise generated by this pump is noticeable. Most tanks are louder then mine, so most people will not have problem with it. Right now i will keep it on constant mode, switching only to pulse when tv is on and kids running around. They kill the noise, lol. Hopefully it will become quieter with time. Overall it is a good pump with much better price point then Vortechs. We will see about longevity as time goes by. I am keeping my tunzes as a back up , just in case it fails or I get tired of noise like i did when i had vortech MP 40'S.
