I have one of these and don't see a thing wrong with it, go ahead and try it. I'm on my second batch out of this this and it is too easy. Personaly I did go by the directions exept for I added a little bear of honey, 1oz of extra hops(strait in the wort)"yes I even heated the second batch a little".,half a pack of yeast and half a pack of the dutch lager. Other than that I dont even have to add more co2, it's in the fridge in 7 days and clear, cold, fresh and really good in 3 more. I'd like another machine if anyone has one for sale
