Same here.

Meanwhile a reliable full size oven can easily cost 1000$/€ and consumes much more energy. Not always cheap/easy to install either.

For people on a budget, who often live in a small/rented place, an airfryer’s a life saver. Plug it in, cook something, pop it away if you need some more space. Don’t even need a kitchen. Just use it next to an open window or vent.

A rice cooker is similarly useful. You can use it to cook far more than rice, keep stuff warm, and largely replace a stove top. Once again, often without the need for space of installation.
