First of all, the Brewhemoth is a very late to the game, and ads no features over any existing product on the market, and that has been on the market, for at least a decade. Secondly, there are many people would would disagree with the combination of features, me being one of them. And lastly, there are products on the market in the same general price range, although perhaps not as well known. And there are features, such as internal racking arms, that are missing.
I wanted a setup that would allow me to ferment, and then to condition. I'd actually prefer to keg condition and carbonate, and may once i have room for a beer engine. What my setup gives me is the ability to brew - and ferment - as fast as the beer ferments. As soon as it's done fermenting, I can move it to a conditioning take to dry-hop, lagger, or simply age (condition). Could you do this with the BH? Sure. But nowhere nearly as easily. As we were talking about on IRC yesterday (several of the members own BH), even taking a sample is more difficult.
As with any product, each user needs to define the criteria by which they can judge, and then apply those criteria to the products available to them. If it brews good beer, I support it!
