Has anyone here used any of these products? They look similar to Mr. Beer refills,but are cheaper.I use Mr. Beer refills,but add x-tra DME and do hop boils to improve the batches.I was wondering if you all feel that they are a reputable company.I hate to plunk down some money and then loose it.Also their website is rather vague about how to order etc.I'm intrigued by the shape of their fermenter.I'd like to have one of those.What are your thoughts or info .Thanx in advance for the info.....Randolf
