This scale is one of the most important tools in my kitchen. It ensures accuracy in following (and repeating) a recipe. When you measure by weight, you can double or halve a recipe as you need. And it makes measuring ingredients faster, easier, and cleaner.
The Maestro is a two-in-one scale, with a main scale for weighing heavier items (5 pounds/2.25 kilograms of flour, for instance) and a pop-out small scale for weighing lighter items (such as yeast or baking powder), accurate to one-tenth of a gram. (Measuring in grams is easier and more accurate than ounces; even American cookbooks are adopting metric measurements now.)
