I use mine a lot - all in cream, although 45 years ago I had an "original" wedding present flame casserole which I sadly ruined. I now have a big round shallow lidded one which is great for 6-8 people, a smaller casserole and one with a handle with a lid which also serves as a non stick frying pan,oh and a rectangular gratin dish which is also brilliant. I did buy some cheap copies from the Daily Telegraph a few years ago, but don't use them as much and also 2 very heavy non-stick French lookalikes which I bought in a cash and carry near Calsis years and years ago. They are good for huge numbers.
What I like is that I can use them on the hob, in the regular oven and in my slow oven and then serve straight from them at the table.
