I've used these pens in the past and had a great experience using them for work so I bought a dozen of them. This batch that I received does not write smoothly and the ink seems to skip as I am writing. Not sure if it is just a poor batch or if perhaps the pen quality is not as great as I remember.
They write great and don't smear which is huge. The expensive pens I was buying would quit working sometimes with plenty of ink left in them but the roller ball would just quit. These so far I've not had a problem.
