One of the major drawbacks of liquid ink rollerballs, like the Precise V5 is that it will not write effectively over white out (found that out in the fifth grade...)
Also, being an Extra Fine pen, the tips are fairly fragile, and I have experienced moments where the tip will fall out on its own.
Its looks and design don't really earn a ten in my mind, as the design is fairly crude for ease of manufacturing.
The smoothness really depends on the paper you use. On poorer grade paper, the point WILL go through if you apply enough pressure.
And even though it IS an extra fine pen, because of its liquid ink, the line it puts down is usually the same thickness as a medium ball point, if not just a tad thinner.
