I have had my Robobrew 3 since last June and have brewed 7 batches on it and I am very pleased with the system. In 10 yrs of brewing I have done it all from extracts to steeping grains, to BIAB, traditional all grain, to using a simple HERMS...I really just wanted to simplify my process and this has it all in one package. I brew slightly smaller batches and I brew full volume mash, no sparge which saves me time and a step there. I love being able to set up the delayed start and have the strike water ready for me when I get up in the morning, pour some coffee and dough in. Efficiency with the no sparge is 70%, time and effort needed is really reduced from my past methods and the beers speak for themselves.
