What a lovely, thoughtful kind of present for your daughters, MayBeMaw! Everyone should definitely have an auntie like that!
We have a Le Creuset casserole which we got for a wedding present 45+ years ago, and it is still going strong, although now mainly when we have visitors as it is quite big. The milk pans with a pouring spout are excellent too, we find. My DF passed on a pan with a lid which works as a frying pan to us when he found them too heavy, and I suppose one day we may feel that we have to pass them on to the next generation.
(No idea about using them on an induction hob though, sorry.)
