Now we all can't say that Mr.Beer is no good ect, ect, ect. For many people (including my self) started out with Mr.Beer. I made 2 batches with Mr.Beer and then went to a full kit and haven't stopped.
Are you missing anything? Not really but if you have a 2 1/2 gallon bucket go a head and try out one of there kits.
So Mr.Beer deserves a little credit. After all it got many people started in this hobby, obsession. So personally I owe thanks to Mr.Beer.
