FastFerment 7.9 Gallon Conical Fermentor

I recently saw this fermentor pop up on northern brewer.com. I can't find any reviews on it. I'm curious to know if it's as useful as it appears and/or does it have major flaws and should be avoided? I like the idea of not racking into a secondary or a bottling bucket.. Seems like it would certainly limit the risk of contamination and eliminate a lot of cleaning. The amount of headspace bothers me a bit. I'm making 5 gallon batches and it seems like there would be a lot of air exposed to the beer over the 4 week process. Any thoughts?
