It's honestly kind of nice for trivial decision-making. The d2 displays H/t instead of 1 and 2, so it's an actual coin flip. Other than that, I just wanted it for the novelty, pulling it out during D&D was hilarious.
Die are great for decisions you don’t care about. Assign options for eating lunch, say, to numbers, roll the die, if you feel the need to fudge the result now your actual preference is revealed.
