Yea I've had beef with lots of his claims and I've seen the fake logs all over the place but there is one log here in on pm by "barny" I am fairly sure is legit which convinced me to purchase it from him. It's been working for me so no complaints.
Again not saying go buy his product I'm just saying what I'm using, someone knowledgeable with brewing their own could probably be using it at a tenth of the price.
