I have one piece (6 quart) and really like it. The odd shaped handle on the lid lets you rest it in the slot on the pan's handle where any drips run back into the pan. I like the indicator which tells you when to reduce heat, and the lid can be turned one way to seal tightly and another to let steam escape. I think it was worth the money and plan to invest in more pieces. The only drawback is that because of the indicator, the lid must be hand washed.
