I used one for almost a year and really liked it.
I used it on the return from sump via a Eheim 1262 in a 60g tank and it was the only flow I needed (LPS not SPS).
I have switched things up and now use 2 nano streams for flow, not due to any fault of the wavysea, but because I have become a member of the slow flow through the sump club.
There is one design flaw with the wavysea though - it loses it's memory when powered down.
In most cases not a big deal as reprogramming takes all of 12 seconds.
oh, and you're in luck:
