I have used these pens for at least a few years now -- I am pretty-much a dyed-in-the-wool Paper Mate pen fan. These pens are inexpensive and they write sooooo smoothly! The colors really are vibrant, unlike all the other colored gel/ink pens I've tried -- especially the green. Whenever I have loaned any of these pens to someone, I have to "struggle" to get it back (lol!) because everyone loves how they write! I have never experienced ink linkage issues with these pens. Additionally, the barrel-size and rubber grip are comfortable to hold. I love the clear barrel feature so I can see how much ink I have left, too! The only VERY minor thing that might matter to someone who needs a sturdy clip on their pen(s), the plastic clips can break more easily; but, Paper Mate has solved that design aspect with their "Elite" version (of these exact pens) that have metal clips, which are SLIGHTLY more expensive. Ultimately, great pens at a super price!
