I like how heavy they are, and the dice make a satisfying thunk when they hit the table.
I only have two gripes about them:
First is that the edges are a bit sharp. After all, if I wanted to teach my younger cousins how to play table top games, these dice would be too sharp for their hands.
Secondly, when rolling I’ve tended to land disproportionately on lower numbers (below ten), and I don’t know if it’s because of my terrible luck, or if it’s lighter near higher numbers.
