Any comments? DH bought a rice cooker a few months ago but the non-stick coating is coming off so we can't use it any more. Was considering getting a multicooker. Already have just about every gadget under the sun so was wondering whether it is worthwhile getting one of these. I've been looking at the Tefal multicooker but don't much like non-stick coatings. Is this one likely to last to make it worthwhile the price?
