I am new to making kefir, so I can't compare/contrast for you. But I can offer that Fusion Teas delivered kefir grains that amazingly healthy, and they provide an ebook with the purchase that is quite informative.

Whatever you do, don't listen to the idiot telling you to "make them yourself". You can't "make" grains. You're gonna have to acquire them from somebody. Many people here (including myself) bought grains from THIS SELLER on Amazon.

Homeade Kefir is amazing for bringing digestion back to normality. I used this starter kit from amazon: http://www.amazon.com/1TBSP-Active-Organic-Kefir-Grains/dp/B007GGRJTG/ref=sr_1_2?ie=UTF8&qid=1427740715&sr=8-2&keywords=kefir
