Homebrewed beer rules, but this contraption seems pretty shitty. You are better off to invest in the proper equipment which should cost around $80-100, and sometimes comes with a cheap beer mix and yeast. You will also need a stainless steel pan to boil water in, spring water preferrably. You need other stuff like sugar for carbonation and I would invest in some hops and flavorings separately because most individual kits taste like shiat. Get the book on Homebrewing by Michael Jackson and no I do not mean the sandblasted pedefile, this is a different Michael Jackson. The cool thing is that after the intial investment, you onlye need like $40 bucks and you can buy enough ingredients to make 50 beers.
