Good quality in the mug and, surprisingly, the coffee itself.
The mug has endured knocks and drops with little-to-no damage.
The coffee is rather nice too. I was semi-expecting a 'bleurgh' and tacky taste, but was pleasantly surprised using it (in a Bialetti), even better when a dash of actual JD is added!
The only gripe is that the picture shows a tin, and a tin is not what it arrived in - it was in fact, as previously stated by another reviewer, delivered in a cardboard presentation box. A tad annoying.
