I love, love, love my countertop convection oven. I use my regular oven as storage now. My convection oven cooks faster, better, and also has a rotisserie option. I never use it on regular rather than convection. Uses less electricity too and doesn't heat up my house in the summer. I live alone and for one or two people, it's the best.
I also have an Aroma 3 in 1 Grillet. Steam, Grill, or Simmer. Basically, it took the place of my George Foreman Grill, my stovetop, and my small pans. Only time I have to use the stovetop is if I need a large pot or skillet. Since I live alone, that's really rare. I also have a microwave and a mini Instant Pot, a mini waffle maker, and a coffeemaker which I use as a tea-maker as I don't drink coffee.
Between all these things, I never use the range. I live in a very small apartment with a tiny (seriously itty bitty) kitchen and making use of these things has been a lifesaver.
