Impressed so far. I've made both yogurt and Greek yogurt which has been easy, tasty and cost effective. Machine works well. It's a simple design, so less can go wrong. Instructions are clear.
One tip if you're making Greek yogurt, I found that I needed to strain the whey again as it still contained a fair bit of yogurt (due I think to the quantity) - this then maximised the quantity of yogurt. I then used the whey to make bread, so no waste!
I highly recommend, am very happy
