I have been using this yogurt maker for almost 3 months now. My children love yogurt with every meal. With this machine I always have it on hand.The yogurt comes out perfectly creamy (I use whole milk).I made the first batch using the starter I bought on this site.The first batch didn't set though and I realised the milk might have been too hot when I added it. I bought a candy thermometer and since then I've not had any problems. The book tells you to use a half cup of yogurt to make a new batch. I have made it using the organic yogurt (with a couple of teaspoons of starter yogurt) from the store and that came out perfectly too.The only thing that doesn't work for me, is the timer(?) dial on the lid, because I am very forgetful. So instead I use the stove timer which will beep to remind me.If you are a yogurt lover, then this machine make a lot of sense.
