I love my yogurt maker. My first batch didn't turn out at all - I tried not heating the milk first (the manual says that should work as long as you are using pasteurized milk). The second batch was delicious, but a little thinner than the store bought kinds we are used to. The third batch I added a bit of powdered milk to thicken it up and it turned out perfect. It is so creamy and smooth. I just add a little brown sugar and it is like I am having a brown cow maple yogurt - yum.
I am actually surprised by how easy it is to make. Seriously, you heat the milk to 180, let it cool to 115, add the starter (other yogurt) and any other fixings (powdered milk, fruit, whatever), pour it into the cute little jars and leave it alone for six hours. The hardest part is not disturbing it for six hours. This is a new staple for us - I feel so frugal just thinking about it.
