I have a 200v induction cooktop. My only complaint so far is that I don’t quite have as fine-grained control as I did with gas, but that doesn’t matter most of the time. It also isn’t heating up and around the pan. In any case, I have a portable casette gas stove if I really want to make Chinese in a wok with high heat and the flame coming up the sides.

My water heater is an eco-cute and does quite well for energy efficiency. It was a bit of a change coming back from instant on-demand gas water heaters, but it’s fine now that I’m used to it.
