Pros:-Easy to use-Simple instructions with a videos-Yogurt tastes greatCons:-Only one yeast packet. So if you don't continuously make yogurt, you will have to go buy more yeast. Could have included a few packs rather than just one.-Overpriced for what you get. It comes with a mason jar, lid, thermometer, and yeast for $30.Overall:Great concept and very easy to use, but expensive. The yogurt tastes great and I will be making more, well I have to unless I want to go buy more yeast.
