These skillets are to replace my ceramic non stick that actually stick.  I put the largest one to work shortly after I got it home.  I love the weight of it on my glass top stove.  It does not seem to slide around like other pans have done.  Because my recipe uses butter/oil I used it and nothing is sticking at all.  If all 3 cook as nicely and evenly as this one, I will be very pleased.
