I have looked at those enabled cast iron cookware pieces several times...I don't know anyone personally who use them. I end up not buying one because when I go to pick it up empty it is very heavy, can't emagine trying to do that when filled with food! Just my reasoning.
my fav kitchen tool is whatever I am using at the time of preparing a meal, imagining how much easier life is for us here and now as compared to the past or now in some primtve areas......
