My children both have one, and use theirs as I do mine - for a mixture of defrosting, heating up leftovers and helping with cooking from scratch.
It's only recently that I have thought of them in terms of saving money - I have used mine as it's quick, convenient, clean and saves on washing up. Now that energy is so expensive I will factor that into decisions on cooking methods, too, although they are largely subliminal or borne of habit.
It's interesting - I was talking to a friend of mine about cooking the other day. She can be rather snooty about 'cooking from scratch', and refused to have a microwave, an air fryer or slow cooker, as 'they are just for people who buy ready meals'. She knows that I (usually) cook from scratch, and that I am a great fan of a kitchen gadget, have all of those things and more, but it didn't stop her from looking down on them - until the energy crisis. Now she's changed her mind and wants to buy them, she is incensed that the prices have risen so much. Obviously it's because of people like her, who are suddenly flooding the shops with orders
