For what its worth it does its objective to highlight what you want highlighted. Reminder this is not a thick highlighter so one may need to go over the parts to be highlighted if the print is a bit bigger than normal. Also one ought to make sure you position the pen when using where the slant goes from up to down otherwise it wont work as well
I really like the quality of this highlighter- great chisel tip perfect transparency- not too dark not too light and it doesn't bleed too much. But I wish there were more color combinations available like green highlighters only or green & yellow or green & pink. I mostly use yellow and green and some pink and wish I could get a pack of only green highlighters.
