I was tentative at first, and like a previous reviewer, I was disappointed with the need to put the edge smoothly against the page to get a true highlight (as opposed to just a bright line), but this was a skill learned with far less frustration than what I experience in a single session of uncapping and recapping traditional highlighters over and over again.

The tip is chiseled so you can have fine line underlining or bold broad highlighting.
