Hey Netix,

I know there has to be a thermos involved somewhere as you have to keep the combined milk and yoghurt warm. I also know you have to heat the milk to the right temperature before adding the yoghurt and if its too hot then it kills the yoghurt but if its too cold it won't set... I know that's not terribly helpful...

Personally I have an easi-yo which I think is great...

Hope you find answers soon,

Ruth
