I've used the Pentel Arts "Stylo" JM20, which appears to be a non-refillable
version of the Tradio for the American market; the unique tip looks exactly the
same, except on the Stylo the plastic part containing the felt nib is
ivory-colored. I'm not excited by it myself. The line variation it gives, while
not dramatic, is an advantage over other felt-tip pens, and the plastic nib does
seem more durable than many felt brush pens. I haven't noticed bleeding, but I
have had the problem of the plastic flicking little hair-lines of ink. For me,
it can't compare to a flexible metal nib or a hair brush.
