4-q round black round mat is my first Staub and I am so happy to write a review. 

First of all, the feature is awesome. It looks very modern with my new kitchen. 

Second, it works excellently. 

I usually use this pot for making stew and soup. 
It boils very fast and keep the moisture from ingredients. 
Eventually, I add less water than I have usual. 
It is perfect size for dinner for 4. 

It is easy to clean, once I clean it with warm water and dry it through heat. 

Last thing is good for oven boiling. 
Sizzling chickens and put it right into oven and I get perfect chicken dinner. 
 

After this purchase, I got a fry pan and a wok. 
They are also my favorite.
