Anybody used one of these yet?

A friend of mine is putting a wet kit on his TPI. Looking for input. He has a chance to get a maximizer cheap. Looks relatively easy to wire in. I'm wondering how hard it is on the solenoids pulsing them. Anyone have a user manual that is downloadable to read through?
Thanks.
