Mad Brewer kit
Excellent book, the rest of the items work as advertised and for a new brewer are should haves. The wine thief works but I'm thinking it could be better but as I said it works.

Mad Brewer/ How To Brew Testing Kit
I received my Mad Brewer Kit today on 1/9/18 Everything was packed perfectly. Very fast shipping too. I also have a new best friend, it is my hydrometer which is a must have item if you want to brew. The kit has the right stuff you need for your beer to come out with good taste and a clear brew. This kit also has a great book on ( How To Brew) By John J. Palmer. This book has everything I mean EVERYTHING! You need to know to brew great beer every time. I don’t think John J. Palmer forgot anything, It’s all there. It even has a chapter on making your own recipe, wow its a thick book. So if you are going to brew beer you better add this to your order, you’ll be glad you did!

Excellent addition to any brew kit
I purchased this kit with the deluxe brewing system, and it was an excellent addition. It made the brew process that much easier. The book is very informative, and an excellent reference text. Plus being able to measure specific gravity and ABV is an fun way to make sure fermentation is proceeding well.
