I've used this since purchased and love it.  Easy as come be and consistenly turns out yogart the way I like it.  I add 1/2C powered milk for increased calcium as I have osteoporsis and 2T of either tapico (preferred) or cornstarch to the standard measurements and set it for either or 13 or 14 hours as I like firmer yogart and don't time or desire to strain and the tarter version.  I top it with my homemade granola and this is breakfast very morning.   It stays with me so I'm not hungry til lunch.  What a great appliance!
