Exactly. Why should a munchkin use a fair die? (I just liked the symmetry of a player "calling Heads" to roll a head.
The idea was to have a 5/6 chance of getting a serious bonus, but a 1/6 chance of a serious penalty.

As you say, people will always select tails, which means in your example they will only get a +1 or 1.
To have an item that is usable only once per game and that only gives a chance (not even a guarantee)
of a +1 seems pretty weak.
