@heavens_feel Since it is specifically for instant coffee think about buying a barista electric kettle: you can finely adjust target temperature with it, and even have it keep the water at that temperature. It's perfect for instant coffee as you can experiment what temperature tastes best. They're not much more expensive than normal electric kettles, I use mine every day.
I thought about getting one of those coffee pod machines but would rather go with the kettle instead. The kettle could also prepare hot water for instant noodles, so it has more possible use cases.
