I have many pieces of Cuisinart kitchen gear and have generally been quite satisfied with them.
For about a year I have been using an air fryer and I love it, but unfortunately 120V appliances are inherently less energy-efficient than 240V.
The trade-off is probably worth it, in comparison to a full-size standard oven, since the volume that must be heated up is so much smaller with less "wasted space" ....
