Easy to hold and has a nice weight to it when I hold it. Not flimsy and not too heavy. Very easy to wash. I can't tell you how long it keeps the coffee hot as I drink it up before it cools down.
Mug is just the right size for that first cup of coffee. I can pour the coffee before I jump into the shower and it's still warm when I get out. I can savor it.
The Loyalty offering is the best in my view - you must try it the traditional Vietnamese way with a touch of condensed milk - so good!
I really like the the size of the mug and how the phin sits on tip. The insulation is excellent as I drink my coffee very slowly. My only gripe is that it doesn't fit in the cup holder in my car. But I blame the car :)
4 oz Phin fits perfectly on top, and it also fits my aeropress!
