Input:
I bought two of this item because people said that a 1 quart Mason jar fit inside it perfectly.  Unfortunately, since those reviews were written, the design must have changed because quart sized mason jars do not fit the yogurt makers that were delivered to me.  The glass jars are too narrow and too tall to work well with it.  Now, unless I can find a short fat quart jar, I am stuck with the plastic liner that came with the set.  Very disappointed. :(
