Would recommend anyone to get this with their first homebrew kit. The book is great to read and to refer to when needed. The measurement tools are essential as well!

Cool kit, but imperfect
The economy test jar had a slow leak at the base, which I fixed with a dab of superglue. The three-piece thief is also a bit leaky but works fine for transferring liquid a few inches from a carboy to the test jar. I learned by reading online reviews that Biofine Clear should not be used when priming beer for bottle conditioning because it removes the necessary yeast; so I wish that was clearly stated on the kit's instructions.

This kit works out very well! I originally bought this for the hydrometer, the extras were a perk. I highly recommend the fermcap. I haven't tried the biofine yet, mainly due to the style of beer I made.

Nice add-on for the beginner brewer
I added this to my initial kit order - with the hope that I would use all the included items during my brewing initiation. I used every item except for the Biofine. Palmers book is a bible, the hydrometer, thief, and test jar are essential to measuring where you are, whirlfloc is amazing, and Fermcap-S has made wort boils so much easier. Biofine may do a fine job clearing but it appears that you have to add more yeast when ready to bottle - not something I want to do

Knowing ABV v/s guessing, No mess brew days, CLEAR BEER!
Kit is wonderful. I can test my batches and have nailed down the specific gravity for a true read of ABV and gravity points. The extras included with the kit are wonderful. I will be using these products on every batch going forward, no foam over during brew day, no blow off during primary fermentation, wonderfully clear beer at the end of bottling. Would defiantly recommend getting this kit if you want to step up your brewing experience and the quality of the final product! Cheers!
