Yep. And their yeast is also rubbish. It has a terrible "woody" flavor and smell to it.
I know people make beer with them, and like them, and that's great. But lots of people make soup with Campbell's Soup and like that as well. And I think it's terrible.
I'm glad that there is something for everyone, but when I made a Cooper's kit as a relatively new brewer, I would have been terribly disappointed and quit brewing if I hadn't made a better kit first and knew it was possible. Since I had made a decent beer out of Brewer's Best kit, I realized it was the crap prehopped canned LME and not homebrewing in general that made a bad beer.
