The markers work great!  I like the fine line.  For me, the wide tip turns out to be a waste.  I apparently am not skilled enough to get them to consistently to color a line of similar width, and the tip is too wide for fine work, which is mostly how I use the markers.  At first, I thought the color choices were weird and not complimentary, but I am starting to change my mind about that as I use them more.  If anything, I wish I had bought a bigger set at this point.
