Sloping gardens

I changed my gas hob for induction very recently and although I have replaced one iron pan because of the weight, I still use my cast iron griddle hot enough to make naan bread. The glass has discoloured slightly, but my main gripe is that the touch controls don't work unless scrupulously clean and dry. 
But in general I'm glad we made the change ... although I have kept a two ring wok burner hob as well
