Mark,
they are working pretty good, have them wired through the profilux, so I can have full control. Trying them as a pulse or wave action right now, it does make the pumps whine a little, that that happy about that, but what can you do. Other than that I do like the ability to have total control, if I want a little more i can always bump it via profilux. All in all, happy with the outcome.
