i have been using 2 units of a similar one from inalsa since few years without any complaints. purchased locally. one of them i use for travel & the other at home.
No advice on the kettle, but I will say that I’ve found Milton’s quality has gone down from what it used to be a few years ago, and their steel quality isn’t great in my experience.
Also, from your list I’d go with Havells because it has a steel lid. Ideally you don’t want any hot water or steam to contact plastic parts.
If you’re going to be using it for milk regularly, then you’d want it to be easy to clean, every nook and cranny should be easily reachable. Your selected products don’t really have that.
Actually my earlier kettle was 1.5l but as I started carrying the kettle for some long stays, I got the 500 ml Prestige one which works great for tea/coffee, but may not meet your needs.
At home I actually use a Hawkins 1L induction bottom saucepan on an induction stove for anything that requires boiling.
