The more expensive competition from yogurt maker works with hot water, this has consumed its own power connection of a few watts.
I like the power prefer, but that's a matter of taste.
For yogurt one first needs yogurt. Whether one buys yoghurt bacterial or my opinion, a plain yogurt with live bacteria does not matter. Gustatory difference makes more milk. I have the impression that the fatter, more firmly.
The containers can be stored and taken out in the refrigerator. The yogurt keeps fresh for a week, after a day he's only really delicious. However, it rarely lasts more than a few days with us.
When the purchase price, including energy costs, I have not recalculated amortized, but knowing what the feeling is in the eating, is more important for me.
Ask the manufacturer and good information obtained: The container is made of polypropylene so BPA free! Great!
