first time purchase when it’s on sale. i follows the other reviewer and add about a dozen cubes. it’s enough for a big pot. the quality is not bad. i washed it very well with baking powder, there is some impurity but it’s not a big problem. simmer for about 45mins and it tastes good and doesn’t have the rubbery taste like the other review said. for the price it’s no complain and i’d buy gain.
