The cup is very sturdy and will last a long time. If full to the top, it would actually be 2 cups. I guess that the extra space on the top is for the cover which i did not get. This is actually a 2 cup with 1 cup marking, it is made for metric reading or cup if you are left handed. I ordered a 1 cup because i use 1 cup mostly and it fits in utensil drawer just below counter. However, you cannot see the markings for cup measurement if you hold the handle with the left hand and pour with the right. I prefer the conversing cup where the metric and the cup equivalent is written on the same area of the cup instead of opposite sides. If the same measurements cup, oz, and metric is written on both sides like it is on other brands it would not matter if you are left hand or right and if you use cup or metric. The measuring is important since even though the cup is a 1 cup you cannot dip a cup full of flour, a cup full which is supposed to be a 1cup would actually be 2 cups.
