After literally years of contemplating setting up some sort of a RIMS/HERMS system, I finally bought a Unibrau v3 a few weeks ago.
I'm pretty much running it stock, though I did add a sight glass from SS Brew Tech, and I'll be using my usual fabric filter bag. Also, I don't plan on boiling in it but rather will pump over to my existing kettle.
I did a test run the other day with a few gallons of water, and everything seems to be working properly. The Auber EZ Boil controller seems pretty straightforward once you mess around with it a bit and figure out the various menu options.
Planning to brew a Saison recipe I've brewed many times as the inaugural batch this Friday
