I've been using the Milton Cosmic mug for my chai and coffee, and it's pretty good! Build quality accha hai, keeps drinks hot for a long time. Only thing is, the strainer could be a bit tighter, sometimes I have to check for leaks. Overall, for this price, it's a solid choice for daily use. My family also likes it for their drinks.

I've been using the Milton Cosmic mug for a few weeks now, and it's pretty good for my morning chai and evening coffee. The stainless steel quality feels sturdy, and it keeps my drinks hot for a long time. Bas, I noticed the lid can be a bit tricky to open sometimes, but for the price, it's kaafi worth it. Perfect for home and office use!
