Since I switched to using 0.9 mm, I almost never break a lead unless I drop it onto a hard floor; it even holds up to some aggressive tapping. Consequently, I hardly ever have to refill. I also never worry about the point snapping or stabbing when tossed loose into a bag, or keeping a sharpener on hand.

Just my #2 cents.
