I personally like self-made yogurts as they are more nutritional and you can cook them from anything you like, not including chemicals and stuff that is not healthy. I bought YMX650 Automatic Digital Yogurt Maker for this purpose(making yogurt on my own). I'm really skeptical when it comes to buying new household items, so I usually need reading reviews and guides in order to make right choice. If you're as doubtful as I am,
and choose the best variant of yogurt maker as they usually have some unnecessary features or some defects, which may be so annoying. This site gives detailed review on every products, including pros and cons.
